摘要
研究了稀土氧化镧对PET结晶行为和力学性能的影响,并与另一种成核剂和PET组成的体系进行了对比。结果表明,稀土氧化镧明显提高了PET的冲击强度和拉伸强度,并且改善了PET的结晶性能,从而有利于加工性能的改善。
The effect of La2 O3 on the crystallization behavior and mechanical property of polyethylene terephthalate ( PET) was studied, and compared with PET filled a type of nucleating agent system. The result showed that La2O3 enhanced the impact strength and tensile strength of PET notably, and the crystallization property were also improved, so it was useful to improve the proces-sability and mechanical property.
