摘　　要：应用钛系聚酯催化剂LT181在25万t连续缩聚PET生产线工程化生产瓶级PET切片。对切片的特性黏度、端羧基值、色值、乙醛含量、二甘醇含量进行检测分析,钛系催化剂能取得和锑系催化剂相似的技术指标。Application of titanium based polyester catalyst LT181 to 25 × 104t continuous polyeondensation PET production line, to engineering production of bottle grade PET chip. The intrinsic viscosity, carboxyl end group val- ue, hue value, acetaldehyde content, DEG content of the chip was detected and analysed. Titanium based catalysts can obtain similar technical indexes as antimony based catalysts.
