摘要

以单质铜(Cu0)为还原剂,采用电子转移生成催化剂原子转移自由基聚合(ARGET ATRP)合成了丙烯酸乙酯-co-3-甲基丙烯酰氧基丙基甲基二甲氧基硅烷(DMMSPMA)共聚物[P(EA-co-DMMSPMA)]及其湿固化膜,研究了P(EA-co-DMMSPMA)分子量增加以及DMMSPMA含量对P(EA-co-DMMSPMA)湿固化膜性能的影响。研究结果表明:随着P(EA-co-DMMSPMA)分子量增大,湿固化膜的拉伸强度增加,断裂伸长率略有上升,玻璃化转变温度升高。在P(EA-co-DMMSPMA)分子量为10000,DMMSPMA含量为25%(wt,质量分数)条件下,其拉伸强度为2.09MPa,断裂伸长率为33%,玻璃化转变温度为4.18℃。
        (Ethyl acrylate-co-3-methacryloyloxypropylmethyldimethoxysilane)copolymer[P(EA-co-DMMSPMA)]and their moisture cured crosslinked films were synthesized via activators regenerated by electron transfer for atom transfer radical polymerization(ARGET ATRP)using copper(Cu0)as a reducing agent.The effects of increase in the molecular weight of P(EA-co-DMMSPMA)and the content of 3-methacryloyloxypropylmethyldimethoxysilane(DMMSPMA)on the properties of moisture cured crosslinked films were investigated.The results showed that with the increment of molecular weight of P(EA-co-DMMSPMA),the tensile strength of films increased,the elongation at break slightly increased,and the glass transition temperature increased.When the molecular weight of P(EA-co-DMMSPMA)was10000 and the content of DMMSPMA was 25 wt%(wt,mass fraction),the tensile strength was 2.09 MPa,the elongation at break was 33%,and the glass transition temperatures was 4.18℃.
