Dilute Solution Behavior of Block Copolymers: Styrene-Methyl Methacrylate and α-Methyl Styrene-Methyl Methacrylate Systems

The structural feature of block copolymers is that each polymer chain consists of chemically different subchains, each being a long stretch of monomers of a single type. Block copolymers in solution exhibit characteristic behavior resulting from thermodynamic inter-actions of subchains with solvent molecules and with each other. The nature of such interactions should resemble, in some respects, to the interactions found in a ternary system involving the parent homopolymers and the solvent. The situation is in contrast to the solution behavior of statistical and alternating copolymers, in which chemically different monomers are distributed along each chain in highly alternating sequences (1,2).
