Question 3: (Polyamides) a) What is nylon's great weakness regarding environmental conditions? b) What are the two most common nylon types called? c) Based on crystallinity alone, would expect Nylon or acetal plastic to have better chemical resistance? d) What is the relationship between Kevlar and nylon (chemically / morphologically)?

Would you expect polyesters to be stabilized by hydrogen bonding? Explain.

What is the process by which polymers are broken down into monomers?  What is added to the polymers during the reaction (what goes into the reaction?)

Repeat unit Explain why the polymer is appropriate for its use. Include the properties the polymer exhibits to justify its use. Polymer Name Use Monomer 1 Polyester

What do the two numbers correspond to in the name “Nylon-6,10?” Write the chemical structure of the repeat unit for “Nylon-4,6".

A basic biological compound contains 40.0% Carbon, 5.7% Hydrogen and 54.3 %  oxygen. It has an atomic mass of 175g/mol. a) Hand draw the displayed and skeletal formula of the above biological compound then determine at least two of the isomers exhibited by this compound. b) Explain how the structure affects the properties of the polymers formed by these isomers.

Based on the representative part of the polymer chain, a) state whether it is an addition or a condensation polymer. b) draw the full structural formula of the two monomers use to synthesize this polymer.

Why is sulfur mustard comparatively less permeable to urethane polymer than polymers like polyethylene. Will a polyethylene gas mask be effective against sulfur mustard?
