| 摘 要： | 采用二硫代苯甲酸苄酯和偶氮二异丁腈组成的引发体系，以可逆加成－断链链 转移聚合方法合成了苯甲酸乙烯酯与马来酸酐及N－取代马来酰亚胺的交替共聚物 。结果表明，所行聚合物具有预期分子量，分子量分布在1.1～1.3之间。在较低转 化率下所得的聚合物均为交替结构，而与摩尔设料比无关。

| Abstract: | Reversible addition-fragmentation chain transfer (RAFT) copolymerization of vinyl benzoate (VBz) with maleic anhydride (MAn) and N-substituted maleimides was conducted, initiated by S-benzyl dithiobenzoate/AIBN system. The results show that the polymers possess predetermined molecular weight with molecular weight distribution as narrow as 1.1～1.3. The polymers possess alternating structure regardless of the monomer feed ratio. |

| Keywords: | vinyl benzoate maleic anhydride controlled polymeriztion reversible addition-fragmentation chain transfer alternating copolymer. |
