顺-1,4聚丁二烯橡胶是合成橡胶中的第二大品种,具有耐磨、生热低等优点,是轮胎胎面胶的重要组成部分。本工作研究了含量少反-1,4聚丁二烯链段的顺-1,4丁二烯橡胶的合成、鉴认及其生胶、母胶和硫化胶的性能。 作者试探了既能使丁二烯反-1,4聚合和顺1,4聚合,又能使内双键打开的钒和钴的络合催化体系, Shun -1,4 polybutadiene rubber is the second largest variety of synthetic rubber, with wear-resistant, low heat, etc., is an important part of the tire tread rubber. In this work, the synthesis, identification and properties of raw rubber, masterbatch and vulcanizates of cis-1,4 butadiene rubber with less content of trans-1,4 polybutadiene were studied. The authors have explored vanadium and cobalt complex catalysis systems that both polymerize cis-1,4 and 1,4-butadiene and polymerise 1,4-butadiene with an open double bond,
