摘要
合成了一系列分子内同时含有酸酯基和醇酯基的内给电子体,并系统地研究了分子中不同基团体积对聚丙烯(PP)等规指数的影响。结果表明:当酸酯基上的取代基为直链烷烃时,随着其体积增大,PP等规指数有所下降;而当醇酯基上的取代基体积不大于苯基时,PP等规指数随着取代基体积的增大而提高;当醇酯基上的取代基为萘基时,等规指数有所下降。
A series of internal donors containing acid ester groups and alcohol ester groups were synthesized.The effects of group size in internal donors on isotactic index of polypropylene(PP)were investigated.The results show that the isotactic index of PP decreases as increase the size of acid ester groups in which the substituents are straight-chain alkanes.While the substituents in alcohol ester groups are smaller or equal to phenyl,the isotacticity of PP increases following the size of the substituents.When the substituents in alcohol ester groups is naphthyl,the isotacticity of PP descends.
