高强度

The comonomer in the copolymer by cat247 is trend to isolated. A few amount of comonomer could make the melting point remarkably decreased and maintain the crystalline at a relative high level. This catalyst can be use to produce the material with low melting point and high intensity such as packing film with low hotsealing temperature. The copolymer by cat24 is characteristic of uniform comonomer distribution and low melting temperature and crystallinity. Therefore, this catalyst could be used to produce LLDPE and POE according the comonomer content; cat246 has a strong copolymerization ability, and the resultant polymer has relatively high blockiness. If this trend is strengthened by adjustment of polymerization condition, the polymer can be used as thermal plastic elastomer with random and crystalline blocks.

由于各个催化剂所产生的聚合物各具特点，所以其潜在的工业用途不同。cat247的产物中共单体趋于孤立分布，极少的共单体即可使熔点明显降低而结晶度仍保持较高水平，有利于制备低熔点、高强度的材料（如低热封温度的包装膜等）。cat24的催化聚合产物无规程度比较高，对降低熔点和结晶度都十分有效，通过控制产物中共单体含量的多少，可以生产LLDPE和POE；cat246共聚合能力强，且产物有嵌段倾向，通过调整聚合条件强化这一倾向后，可以用来生产具有无规-结晶嵌段结构的热塑性弹性体。
