Copolymerization of tert-butyl 3-isopropenylcumyl peroxide with butyl acrylate and grafting of styrene onto the copolymers

摘要

Copolymerization of tert-butyl 3-isopropenylcumyl peroxide (D-120) with butyl acrylate (BA) and grafting of styrene onto the copolymers were studied. Copolymers of D-120 and BA prepared in bulk using benzoyl peroxide as initiator were characterized by IR, H-1 NMR,GPC and DSC analysis, respectively. The compositions of the copolymer of D-120 with BA were determined by analysis of H-1, NMR. spectra. The reactivity ratios of D-120 and BA were determined using the methods of Kelen-Tudos (K-T) , Fineman-Ross (F-R) and Yezrielev-Brokhinal-Roskin (YBR), respectively. Graft copolymers were obtained by the grafting of styrene onto the copolymers during the decomposition of peroxy bonds of the copolymers. [References: 30]
