Problem 2. You are given a sample that has been identified spectroscopically as containing equal amounts of styrene and butadiene monomers. You figure out that there are three possible microstructures. It could be: (a) A high molecular weight 50:50 (by weight) styrene/butadiene random copolymer. (b) A 50:50 (by weight) block copolymer of styrene and butadiene consisting of high molecular weight blocks. (c) A 50:50 (by weight) immiscible blend of high molecular weight polystyrene and polybutadiene. Given that the Tgs of polybutadiene and atactic polystyrene are -60 C and +100 C, respectively, and with suitable explanations, explain what you would expect to see in a DSC experiment for each of these possibilities.
