1. In the formation of the glyptal resin, when the reaction appears to boil, what substance is actually boiling off? 2. What is the purpose of the NaOH in the nylon experiment? (hint- what small by-product molecule is formed in this reaction and what would NaOH "do" with this molecule?) 3. In the polyvinyl alcohol gel, what type of bonding is occurring between the borate and alcohol molecules? 4. What is the purpose of the benzoyl peroxide in the formation of poly(methyl methacrylate)?
