摘要

根据Carothers和Flory建立的理论，单体的化学计量控制对于aa型和bb型单体在单相溶液中高效的分步生长聚合是必要的。本文综述了非典型非化学计量步长聚合（NSSP）合成高分子量聚合物的最新进展。反应中间体机制（RIM）和分子内催化剂转移（ICT）系统对于高效的NSSP至关重要，可以产生比理论预测高得多的分子量聚合物。NSSP系统在精细合成技术中为生产适合特定应用的复杂多功能聚合物提供了许多优势。

Recent progress in nonstoichiometric step-growth polymerization

According to the theory established by Carothers and Flory, stoichiometric control of monomers is necessary for efficient step-growth polymerization of AA-type and BB-type monomers in a single-phase solution. This review examines recent progress in synthesizing high-molecular-weight polymers via atypical nonstoichiometric step-growth polymerization (NSSP). The reactive intermediate mechanism (RIM) and intramolecular catalyst transfer (ICT) systems are essential for efficient NSSP, generating polymers with much higher molecular weights than theoretically predicted. NSSP systems provide many advantages in fine synthetic technologies for producing complex multifunctional polymers suitable for specific applications.
