摘要

遥爪聚异丁烯(telechelic polyisobutylene

TPIB)是一类含有反应性端基的重要高分子材料，可作为润滑油、燃料添加剂、密封剂、涂料而直接使用，也可作为反应性原料与带有其他活性基团的原料反应制备功能性高分子材料。正是基于含链端反应性基团的特性，TPIB在功能性高分子材料的合成与应用中占据重要地位。本文综述了近年来国内外TPIB制备方法的研究进展，重点介绍了以在活性阳离子聚合过程中引入具有特定官能的引发剂和终止剂为代表的直接法，以及以聚合后改性为代表的间接法，并对以上2种合成策略进行了对比分析，总结了基于阳离子聚合制备TPIB所面临的关键难题，最后对TPIB未来的发展趋势进行了展望。

Abstract

Telechelic polyisobutylene (TPIB) is a significant class of high molecular weight materials characterized by reactive terminal groups

which can be utilized directly as lubricants

fuel additives

sealants

and coatings

or serve as reactive precursors for the synthesis of functional polymers through reactions with other raw materials containing active functional groups. Owing to its unique property of possessing chain-end reactive functionalities

TPIB play a pivotal role in the synthesis and application of functional polymers. In this review

recent advancements in TPIB preparation both domestically and internationally were elucidated

with emphasis on direct methods that involve the incorporation of specific functional groups into initiators and terminators during active cationic polymerization

alongside indirect methods exemplified by post-polymerization modifications. A comparative analysis of these two synthetic strategies is presented

and the key challenges encountered in TPIB production

via

cationic polymerization are highlighted. Finally

prospective trends for future developments in TPIB are discussed.
