Polymeric Materials Essay

Many modern industries use plastics and other hydrocarbon forms like polystyrene in their products because of their qualities, values and properties. For example our food industry. Our food packaging consists of plastic rapping, containers and bags which is made from

We found that Polypropylene was our 5th unknown. Polypropylene (C3H6) or more commonly referred to as PP, is used for labeling, packaging, textiles, and stationery. In 1957, the crystallization of polymer was discovered. Soon fabric was made from the polymer, and was in high demand. It can also be used for moldings of cars, film, tape, foam and carpet. Polypropylene can not be glued to any objects or itself, and so it is melded. After Polyethylene, Polypropylene is the highest produced synthetic plastic. Polypropylene also holds up well over time, which is one of the reasons that it is the second most produced plastic. The melting point is between 130-171 degrees celsius. Because polypropylene is tough and flexible it can be used as an engineering plastic. Finally, polypropylene can be used be manufactured into a living hinge. A

The Graduate is a 1967 film directed by Mike Nichols who won an Oscar for his direction.  This hit of the 60's focuses on the development and the maturing of the ultra-naïve college graduate Benjamin Braddock.  This movie is about "just one word...Plastics."  Mr. McQuire sums up this entire movie when he tells Ben that there is "a great future in plastics."  In this film the relationships, except the one between Ben and Elaine, are like plastic because they are not real, they are molded, and they are artificial. 

If you have a home with a garage, you have so many possibilities in terms of transforming this area. In order to make this area a better place to be, whether it’s for work or fun, these steps can be taken.

Post World War II plastic started to become a way of life. Early plastics were made from cellulose and also known as "green plastics" but most of today's plastics are made of hydrocarbon molecules that is used from the refining of oil and natural gas. Depending on how the plastic is made will decided wheter it's used for something like sandwich wrap or making some sort of plastic handle on a tool.

Polymers have been changing the way we live for over 100 years. Their availability and diverse qualities ensure that they are always in high demand, and new polymers are always being discovered. Where does this leave the now commonplace polymers which once were ubiquitous in commerce? Polymers such as polyoxybenzylmethylenglycolanhydride (Bakelite) and polytetrafluoroethylene (PTFE) were first synthesised in 1907 and 1938 respectively, making them old by polymer standards. Although the original polymer applications are now redundant, they have found uses in new areas of society. This dynamic aspect of polymers is due to their unique structure. Polymers are created from many small molecules (or monomers) reacting with each other, and arranging

"Plastic" entered the world through chemistry in 1909 and was originally coined to describe Bakelite, the first fully synthetic resin. What make's plastic so unique is when it is heated it can be molded but it retained its shape when cooled (Reddy, 2010). The modern plastic bag was not possible until the accidental discovery of the first industrially practical method of polyethylene synthesis in 1933. Fast forward to today, the use and

The HDI/PCN/BD stoichiometric ratio for the synthesis of the final polymer was kept as 4:3:1. The polymer solution was passed through a Teflon filter in order to

Through the mixing of compounds and the use of a boiling technique three different polymers were formed. Polystyrene was formed by additional polymerization. The other two were formed through condensation polymerization, the difference being that Bakelite had a cross-linked design occur in the polymerization process, whereas nylon 6, 6 did not.

A look at the history of polymers reveals that many of the first discoveries were accidental. Since these discoveries, a whole new area of chemistry

If you look around yourself you may notice that a great amount of the things around you are made up of plastic. You may also notice that all these plastic objects are different. For example, some are more durable while others are more delicate. There are many different types of plastics that exist; different plastics are used for different things. Polypropylene is a very common plastic, one that in some way, shape or form, we likely use everyday. According to a Britannica article, polypropylene is “a synthetic resin built up by the polymerization of propylene” (Britannica, 2016). What this really means is that polypropylene is a synthetic compound made up of propylene that goes through the process of polymerization, which is when monomers are

Polypropylene inherent properties of high firmness, great elasticity and inactivity toward acids, antacids and solvents has secured its position in an extensive variety of shopper and mechanical items (Kawasumi et al., 1997). The density of PP is between 0.895 and 0.92 g/cm³. Therefore, PP is the commodity plastic with the lowest density. With lower density, moldings parts with lower weight and more parts of a certain mass of plastic can be produced. Unlike polyethylene, crystalline and amorphous regions differ only slightly in their density. However, the density of polyethylene can significantly change with fillers (Tripathi, 2001). Polypropylene are likewise adaptable and can have high stretching before breaking. Polypropylene is also the

Polyester fibers are produced from a chemical reaction between an acid and an alcohol. When this reaction occurs two or more molecules combine to make a large molecule in which the structure repeats itself throughout its length. Polyester fibers commonly form very long molecules that are very sturdy and strong (Madehow, 2016).

In 1937 two German workers produced a new polymer that had advantages over existing plastics made from polycondensation and was not covered by existing patients like that of Wallace Carothers polyesters patent. This polymer was polyurethane. Polyurethanes belong to the family of reaction polymers, which also consist of unsaturated polyesters epoxies and phenolics, it is produced by reacting an isocyanate containing two or more isocyanate groups per molecule with a polyol containing on average two or more hydroxy groups per molecule in the presence of a catalyst or by activation with ultraviolet light. The properties of polyurethane are directly related to the polyol, and isocyanates used. For instance, high amounts of crosslinking produce

Though polymers are a very beneficial thing now, but In the future I believe that at the very best that they will only hold the same value to society. I say this because polymers are not a very complicated item and it would be difficult to better this technology in a drastic way. The only further advancements I see are people discovering ways to make polymers stronger, more durable and better suited for extreme and
