摘要
综述了钕系稀土催化体系下催化合成共轭二烯烃橡胶(顺丁橡胶、异戊橡胶和丁戊橡胶)时分子量及其分布的调控方式,总结了分子量及其分布对产物结构及性能的影响,提示了这些调控规律对于共轭二烯烃橡胶产品工业放大试验所面临的问题和机遇。
The molecular weight and its distribution adjusting methods of conjugated diene rubber(cis-1,4-polybutadiene rubber,isoprene rubber and butadiene-isoprene rubber)catalyzed with neodymium based rare earth catalyst systems were reviewed,and the effects of molecular weight and its distribution on structure and properties of the products were summarized with 27 references,the problems and opportunities faced by these regulation rules for industrial scale-up test of conjugated diene rubber products were also pointed out.
