摘　　要：用放大实验制得了 PEN- PET共聚酯 ,通过双轴拉伸制成薄膜 ,对薄膜的干热收缩率、声速取向因子和力学性能进行了研究 ,同时研究了萘二甲酰含量、拉伸工艺等的影响规律。结果表明 ,随着 PEN含量的增加 ,共聚酯薄膜的干热收缩率降低 ,声速取向因子增大 。Several PEN-PET copolyester films were prepared. The shrinking property, the sonic orientation property and mechanical property of these films were studied. The results show that the increasing of the PEN content results in decrease of the shrinking, increase of the oriental factor, and decrease of the breaking elongation.
