Development of fiber-grade PBT

Huang Juan (Engineering Plastics Plant of Yizheng Chemical Fiber Group Co. , Yizheng 211900)  
A fiber-grade PBT was prepared from purified terephthalic acid by esterification. The effect of the performance of PBT on the spinnability was discussed by variance analysis. The influential factors on the terminal carboxyl group content of PBT were studied by orthogonal experiments. The results showed that the thermal properties and relative molecular weight distribution had no evident effect on the spinnability of PBT when the content of terminal carboxyl group had a profound effect. The content of terminal carboxyl group can be controlled under the optimal conditions as followed:catalyst concentration 120μg/g, esterification temperature 240℃, stirrer rotary speed of final condensation reactor 5 r/min.
