摘 要:結構調節劑可用于陰離子聚合中調節聚合物各單體微觀(guān)結構及其共聚物序列分布。綜述了結構調節劑的分類(lèi)及其作用特點(diǎn)。以丁二烯聚合為例,概述了關(guān)于制備高乙烯基聚烯橡膠的調節劑體系。指出結構調節劑今后的主要發(fā)展方向,即設計“高性能、低用量、低氣味、易回收”的調節劑分子和開(kāi)發(fā)“微觀(guān)結構可控性好,序列結構可穩定調控”的調節劑體系。 |
關(guān)鍵詞:陰離子聚合;結構調節劑;高乙烯基聚丁二烯橡膠 |

Abstract:In anionic polymerization, structural modifiers play a key role in controlling the microstructure of each monomer in the polymer and the chain distribution of its copolymers. In this review, structural modifiers are categorized by structure and action, and the actions of the various types of modifiers are discussed and summarized. Taking butadiene polymerization as an example, we have compiled information on the modifier for the preparation of high vinyl polybutadiene rubber (HVBR). The main areas of future development of structural modifiers include the design of molecules that have “high performance, low dosage, low odor, and easy recovery and the development of systems that have”good control of microstructure and stable regulation of sequence structure. |
Key words:anionic polymerization; structural modifiers; high vinyl polybutadiene rubber |
