| Abstract: | Poly(vinyl acetate) with low polymerization degree had been prepared through radical polymerization using AIBN as initiator in methol solution. The effects of the preparation conditions, such as polymerization temperature and polymerization time, vinyl acetate concentration, AIBN amount, etc., on the polymerization ratio were investigated. It was found that the optimum polymerisation was at V(vinyl acetate)/V(methol)=45~65: 55~35, 65℃ , 4 h using 0.2%AIBN as initiator. |
