【Abstract】 Statistical copolymerlzation has been performed for two binary systems using1- methoxy-2-methyl-1- trimethylsilyloxy propene（initiator）and tetrabutylammonium bibenzoate（catalyst）in tetrahydro-furan solution,The copolymer compositions were determined by elemental analysiS for nitrogen and the re-sultS evaluated by the Kelen- Tudos method. The monomer pairs concerned are①acrylonitrile（AN）andbutyl acrylate（BA）,②AN and dibutyl malcate（DBM）.The reactivity ratios determined in this study are:①r_AN =4.08,r_BA=0.06;②r_AN=1. 38, r_DBM=0. 06. Homopolymer of DBM was obtained by grouptransfer polymerization and anionic polymerization respectively.更多还原
