Structural transition in block and gradient copolymer
WebAROP resulted in the formation of strongly tapered, block-like structures. Furthermore, post-polymerization functionalization of the reactive chloromethyl groups by nucleophilic displacement was investigated for the copolymers. Copolymerization of EO and ECH offers WebThis chapter is aimed to give the fundamentals of block copolymer self-assembly. First, we shall focus on the physics of block copolymers in their bulk state. We will describe the … how to perform a wsreset
