摘要

环氧化天然橡胶（ENR）分子链中存在易开环的反应性环氧基团，环氧基团的开环反应为ENR进行进一步的改性提供了极大的方便。ENR选择性氢化双键可以提高其抗热氧稳定性；ENR与胺类化合物和含磷化合物的反应，可以将防老剂和阻燃剂负载到ENR分子链上，从而达到在分子尺寸的分散；可以利用环氧基团的选择性氧化裂解制备NR基嵌段共聚物的前驱体遥爪型NR；通过环氧基团可以进行接枝改性其它聚合物；此外，分子链中的环氧基团使ENR与无机填料和其它极性聚合物共混相容性提高。

Abstract

Reactive epoxy groups exists in epoxidized natural rubber (ENR)

which provided a great convenience for further modification of ENR based on the ring-opening reaction of epoxy groups. Selective hydrogenation to double bond of ENR can improve the thermal stability. Antiager and flame retardant can be loaded to the molecular chain of ENR by the reaction of epoxy groups with amine compounds and phosphorus compounds so as to achieve the molecule-size dispersed state. Also telechelic NR can be prepared by selective oxidation degradation of epoxy group of ENR

which can be used for precursor of block copolymer of NR. a modification with other polymers can be realized by the reaction based on epoxy groups. In addition

ENR has well compatibility with inorganic filler and other polar polymer in blend due to the presence of epoxy groups.
