摘要
Abstract
Based on the assumption that single radical termination is the main way of termination reaction of radical solid phase graft polymerization,the graft polymerization mechanism and the graft polymerization rate model were proposed.The effects of monomer concentration,initiator concentration,and temperature on the polymerization rate during GMA grafting onto PP were investigated.The results show that:the initial polymerization rate is 1.57 power of monomer concentration,and is 0.48 power of initiator concentration,the polymerization rate and temperature obeys Arrhenius equation.The value of the apparent reactive energy (Ea) is 86.63 kJ/mol.关键词
