Question Step-growth polymerization is another method used to make countless polymers, such as polyethylene terephthalate (PET), Nylon, Kevlar, and polyurethane Let's take a look at how polyurethanes are made Step 1: The alcohol (ethylene glycol) is deprotonated to form an alkoxide Step 2: The alkoxide attacks the electrophilic carbon of the isocyanate Step 3: The nitrogen is protonated to give a carbamate intermediate Step 4: Another alkoxide attacks the isocyanate (red) to form...

Draw the structure and indicate the repeating unit of Nylon-8,5, using the convention that the polymer you prepared is called Nylon-6,10. Based on the reaction you performed, what are the names and structures of the reactants you would use to prepare Nylon-8,5. Use structures to describe three possible end-groups for a Nylon-8,5 polymer molecule that was prepared.
