Block Copolymers

Block Copolymers

 

polymers having macromolecules in which comparatively long sequences of the links of one monomer (blocks) alternate with blocks of another monomer. The macromolecule of a block copolymer may be represented schematically in the form ~ AAAABBBB . . . BBBAAAAA ~, where A and B are monomer links of a different chemical nature.
