Summary of Block Copolymer Systems

Most of Chapter 4 has emphasized block copolymers based on, for example, combinations of polybutadiene with polystyrene, where both components are amorphous. The multiblock copolymers were treated in Chapter 5. The system poly(ethylene oxide)-polystyrene, containing one amorphous and one crystalline component, and the crystalline-crystalline block copolymer polyethylene-polypropylene were treated in this chapter. These three chapters illustrate some of the differences that can be brought about by considering the different types of polymers that can be attached to form block copolymers.
