摘　　要：通过将易水解钛化合物与乙二醇、缓释剂反应形成凝胶并进一步氧化处理,获得一种具有纳米尺度、化学式为C_(4)H_(9)O_(5)Ti的高活性抗水解钛系聚酯催化剂,其在乙二醇中经常规搅拌或超声波分散后,颗粒粒径分布约在20~40 nm,在催化聚酯缩聚反应中催化活性约为锑系催化剂的39倍,并使聚酯的亮度值提高约15%。By reacting easily hydrolyzable titanium compound with ethylene glycol and slow release agent to form a gel and further oxidation treatment,a high-activity hydrolysis resistant titanium polyester catalyst with nanometer scale and chemical formula of C_(4)H_(9)O_(5)Ti is obtained,which is in ethylene glycol After conventional stirring or ultrasonic dispersion,the particle size distribution is about 20~40 nm.The catalytic activity in the catalyzed polyester polycondensation reaction is about 39 times that of the antimony catalyst,and the brightness value of the polyester is increased by about 15%.
