摘要
详述了退火对PC/PET共混物性能影响的研究结果,结果表明,由于共混物中PET的结晶速率较慢,在成型周期内难以完成结晶,所以退火对共混物力学性能影响较大。一般情况在165℃下退火12h后,共混物的性能趋于稳定。
The paper deals with the study on the influence of annealing upon the properties of PC/PET
blend. The result shows that the properties of the blend were affected strongly by annealing be-
cause the crystalline rate of PET was so slow that the crystal could not reach the integrity level dur-
ing the processing. The properties of the blend would be unchanged after annealing for 12 hours.
