The Reactivity Ratios of Group Transfer Copolymerization of Acrylonitrile with Methacrylates

Abstract

Abstract: Random copolymerization have been performed for three binary systems using 1-methoxy-2-methyl-1-trimethylsilyloxy propene(initiator) and tetrabutvlammonium bibenzoate(catalyst) in tetrahydrofutran solution.The copolymer compositions were determined by elementary analysis for nitrogen and the results evaluated by the Kelen-Tudos method.The monomer pairs concerned are (1)acrylonitrile(AN) and methyl methacrylate(MMA),(2)AN and ethyl methacrylate(EMA),(3)AN and butyl methacrylate (BMA).The reactivity ratios determined in this study are:(1)r_AN=10.22, r_MMA=0.07;(2)r_AN=5068,r_EMA=0.16;(3)r_AN=8.59,R_BMA=0.09.

Key words: Group transfer polymerization, Reactivity ratio, Acrylonitrile, Methylmethacrylate
