1. Draw the polymer expected from reaction of phosgene with hydroquinone. What category of polymer is this?

2. A mixture of styrene and methyl methacrylate gives different products depending on the type of initiation. With cations, only polystyrene is formed; with anions, only PMMA is formed; with radicals, a 1:1 alternating copolymer is formed. Explain each of these observations. In particular, explain why a 1:1 alternating copolymer is formed with radical initiation.
