结果表明，通过NPG共聚改性的PET的结晶能力随NPG用量的增加而降低，热收缩能力有了明显的提高；无定型区增大，获得了在通常情况下不能结晶的PET无定型材料，从而使改性PET薄膜在拉伸时保持较高的取向度，并在高于其Tg时发生解取向热收缩；拉伸温度、拉伸倍数等拉伸工艺对于聚酯薄膜的热收缩率有着显著的影响。

The results showed the crystallinity of the modified PET decreased with the increase of the content of NPG, but the heat shrinkability was improved obviously. Amorphous polyester material that would not crystallize under usual circumstances was obtained, which made the modified PET film to be able to achieve a high degree of orientation during stretching, and it was heat shrinkable when the ambient temperature was higher than its T the effects of different drawing temperature and DR on heat shrinkage of copolyester film was discussed.

According to the different orientations of domain walls with respect to the (100) observation plane of a foil, 90°domain boundaries may be divided into two kinds. one is thin lens or ring shaped a-a 90°domain boundary, and the domain wall lies on the {110} plane; Usually, most of these domain boundaries are uncharged; according to the extinction rules for the (011) domain walls, the displacement vector 〓 along 〓 can be dertermined, which is parallel to the line of intersection between the domain wall and the plane consisting of spontaneous polarization vectors on both sides of domain boundary; from selected area electon diffraction of crystals including domain boundary, we not only examine slight difference in the crystal parts on both sides of the domain boundary, but also obtain crystallographic relationship between them, that is, there exists a 180°rotation symmetry operator along a normal of domain wall. The other is Z or ring shaped a-c 90°domain boundary along {010} direction, and the displacement vector 〓 runs along 〓 direction.

根据界面相对于样品中(100)观测面取向的不同，90°畴可分为两类：一类为薄透镜片状或环状的a-a90°畴，其界面平行于{110}，多数不带电，由消光规律可确定其位移矢量平行于畴界面与自发极化所在平面的交迹，即，〓方向，而从包含畴界的选区电子衍射图可知，这种不带电的90°畴界两侧存在微小的取向差，其界面两侧的结晶学关系为以界面法线为二次轴的旋转关系；另一类为Z状或环状的a-c90°畴，其界面平行于[010]或[001]，相应的位移矢量为〓方向。
