摘要
To avoid the damage to catalytic system in ATRP by the carboxyl groups in vinyl benzoic acid, a well defined poly( p vinyl benzoic acid) was synthesized via ATRP in the tertiary butyl ester form. The ATRP of t butyl p vinyl benzoate ( t BVB) was studied kinetically. The results showed that t BVB can be polymerized in a controlled way by ATRP. It was found that the polymerization rate of t BVB is much faster than that of St, meaning that the electron withdrawing ester group affects the polymerization obviously. Well defined diblock copolymers of St and t BVB were prepared by using bromo terminated PBVBs as macroinitiators via ATRP. After removal of the t butyl group by hydrolysis, well defined amphiphilic diblock copolymers of styrene and p vinyl benzoic acid (PSt b PBVA) were obtained.
To avoid the damage to catalytic system in ATRP by the carboxyl groups in vinyl benzoic acid, a well-defined poly(p-vinyl benzoic acid) was synthesized via ATRP in the tertiary butyl ester form. The ATRP of t-butyl p-vinyl benzoate (t-BVB) was studied kinetically. The results showed that t-BVB can be polymerized in a controlled way by ATRP. It was found that the polymerization rate of t-BVB is much faster than that of St, meaning that the electron-withdrawing ester group affects the polymerization obviously. Well-defined diblock copolymers of St and t-BVB were prepared by using bromo-terminated PBVBs as macroinitiators via ATRP. After removal of the t-butyl group by hydrolysis, well-defined amphiphilic diblock copolymers of styrene and p-vinyl benzoic acid (PSt-b-PBVA) were obtained.
