Abstract Nuclear magnetic resonance (NMR) method was developed for the determination of relative reactivity ratios of styrene and methyl methacrylate free radical copolymerization. In order to verify the products as copolymers instead of polymer blends of two kinds of homopolymers, the polymer molecular weight and molecular weight distribution and the glass transition temperature were also characterized by gel permeation chromatography (GPC) and differential scanning calorimeter (DSC). This experiment was rich and systematic in content and therefore could comprehensively improve students' experimental skills and the scientific research ability.
