Early attempts to coat metals with Teflon, poly tetrafluoroethylene, resulted in a polymer layer that peeled off the surface easily. Later attempts gave coatings that were much more durable. What type of adsorption processes are being manifested in either situation? What technical problem had to be solved in order to develop durable coatings?

Macromolecules containing fibrous inorganic and organic fillers in polyolefins like polypropylene and in other semi-crystalline plastic polymers molded under stress or orientated (stress induced) will form trans. crystals epitaxially on the fiber surface in-situ in the polymer matrix. However, without fiber fillers in these same matrix no trans. crystals are formed. If transcrystallinity could be induced in unfilled semi-crystalline molded plastics what would be the outcomes observed in the molded part. What physical chemical changes versus a control molded sample of the same material not be trans. induced? Has the field of polymer science and physical been able to model or predict what factors induce either alpha transcrystallinity or beta transcrystallinity?

11c. Nylon 6 and poly(ε-caprolactone) have similar polymer backbone structure with one carbonyl, 5 methylene and a heteroatom, nitrogen or oxygen, respectively. Each is able to undergo crystallization. However, their thermal transition temperature differs significantly. The glass transition temperature (Tg) for Nylon 6 is 52 °C, whereas the Tg for poly(εcaprolactone) is 112 degree lower than Nylon 6 at – 60 °C. Similarly, the melting temperature (Tm) for Nylon 6 is 223 °C, whereas the Tm for poly(εcaprolactone) is 60 °C. Briefly explain the significant differences in the thermal properties of these two polymers.
When the temperature is 20 ° C, water flows through an ostwald viscometer at 363 s, whose density and viscosity are given as 0.9982 g / cm3 and 1,000 cP, respectively. The flow time of OF2 from the same viscometer at -145.8 ° C was measured as 68 s. Since the density of OF2 at this temperature is 1.523 g / cm3, what is the value of its viscosity?
