Abstract
Poly(methyl methacrylate)(PMMA) was reacted with living poly(α-methylstyrene) at −78°C in a mixture of good tetrahydrofuran and poor methylcyclohexane solvents. The reaction conditions were chosen so as to produce graft copolymers made up of a backbone and only one branched chain (1:1-graft copolymer). Gel-permeation chromatographs(GPC), intrinsic viscosity, infrared spectra, and elemental analysis were used for the characterization of the graft copolymers. It appears from these results that pendant side groups on a backbone molecule were not reacted with equal probability even during the first stage of this reaction, when the dimensions of the backbone molecule were small.
