Title: Segmental interpenetration at polymer interfaces

During the first year of this proposal significant strides have been made in understanding the nature of the interface in symmetric, diblock copolymers and the nature of the interface formed between immiscible homopolymers. Emphasis has been placed on the symmetric, diblock copolymers of polystyrene (PS) and polymethylmethacrylate (PMMA) since these diblock copolymers and the corresponding homopolymers are available over a wide range of molecular weight with narrow molecular weight distributions. In addition, the homopolymers and copolymers can be obtained with different levels of deuteration. Thus, these materials form a model system by which systematic studies on the interfacial behavior of homopolymers and block copolymers can be performed.
