Abstract
Radical copolymerization of Vinyl acetate(VAc) and Vinyl benzoate(VBz) was carried out with AIBN as an initiator in benzene at 60℃. The copolymer compositions were analyzed by UV spectrophotometry. The monomer reactivity ratios, r1(VAc) and r2(VBz) were determined by both the Kelen-Tudos method and the Finneman-Ross method ; r1=0.69(0.66), r2=1.48(1.46). The rate constants of monomers, homopolymers and copolymers were determined. Based on the data from a batch reactor, a copolymerization of vinyl acetate and vinyl benzoate in benzene was studied using a CSTR. The experimental conditions for CSTR studies were almost the same as that of a batch reactor. The residence time and volume were given as 7200 sec and 1.2 L, respectively.

비닐 아세테이트(VAc)와 비닐 벤조에이트(VBz)를 벤젠에서 AIBN을 개시제로 사용하여 60℃에서 라디칼 공중합을 하였다. 자외선 흡수 분광법으로 공중합체 조성을 분석하였으며, 단량체 반응성비 r1(VAc)과 Kelen-Tudos 방법(또는 Finneman-Ross 방법)으로 결정하였다 ; r1=0.69(0.66), r2=1.48(1.46). 단량체, 단일중합체 그리고 공중합체의 속도상수를 결정하였다. 회분식 반응기에서 얻은 자료를 바탕으로 벤젠에서 비닐 아세테이트와 비닐 벤조에이트의 공중합을 연속 반응기(CSTR)를 사용하여서 연구하였는데, CSTR연구에 대한 실험조건은 회분식 반응기의 조건과 동일하게 하였고, Residence time과 부피는 각각 7200초와 1.2리터로 하였다.
