DILUTE SOLUTION TECHNIQUES FOR STYRENE-METHYL METHACRYLATE GRAFT COPOLYMER AND ITS PRECURSORS

摘要

A dilute solution study of styrene-methyl methacrylate graft copolymers and their precursors was carried out. It was found that dilute solution tech?niques are applicable to the study of graft copolymers. However, because of a multiplicity of problems, such as solution color, fluorescence, opacity, microgel, uncertainty as to composition, and molecular weight distribution, a quantitative study and interpretation of the data obtained was not feasible. Light-scattering and viscosity measurements of samples of the graft copolymers and their precursors were made and analyzed.
