You will make Nylon-6,10. What does the 6 and 10 refer to? PROCEDURESynthesis of NylonIn a small beaker dissolve ~ 0.5 mL of sebacoyl chloride in 12 mL of ether. In a smalltest tube get ~ 6 mL (~1/4 of a 6 “ test tube) of 1,6-diaminohexane solution in water.In order to form the good polymer fibers, it is best to not mix the solutions. Youshould try to layer one solution on top of the other. First pour the 1,6-diaminohexanesolution into a 100 mL beaker. Then slowly pour the sebacoyl chloride down the sideof the tilted beaker with minimal mixing. At this point you should see two distinctlayers with a white film at the interface. Hook the nylon which forms at the interfacewith a straightened paper clip and pull slowly straight up as high as possible. Thenwrap it around your large beaker and then continue to wind the polymer around tillthe reaction is complete. Rinse your polymer in DI water to remove any salts or acidthat may be present.Weigh your product and characterize it by…
. If a polymer chain has a molecular weight of 280,000, how many ethylene units does it contain? . Calculate the molecular weights of the repeating units of polypropylene and PVC. Determine Mw for a polypropylene of average degree of polymerisation of 18,000. (Atomic masses of H = 1, C = 12, and Cl = 35). Answer: m(PP) = 42 g/mol; m(PVC) = 62 g/mol; w = 756x103 g/mol.
