摘要
通过对几种聚对苯二甲酸乙二醇酯-1,4-环己烷二甲醇酯(PETG)和聚对苯二甲酸乙二醇酯(PET)原料的热性能、流变性能、气体阻隔性能、力学性能及光学性能进行比较研究发现,PETG中引入了1,4-环己二甲醇(CHDM)使得其分子链的规整性被破坏,难于发生结晶,使得其性能与PET的不同。
Thermal performance, rheological property, gas barrier properties, mechani cal properties and optical properties of several kinds of PETG and PET were compared and studied. It is found that the regularity of the moleculer chain of PETG is destroyed, which influences its crystallization, and the properties of PETG and PET are different be cause of the introduction of CHDM.
