摘　　要：选用EVM 900与HVBR并用来拓宽HVBR在常温下的有效阻尼温域,采用钼系催化剂催化丁二烯在EVM溶液中配位聚合,原位生成HVBR/EVM共混胶。结果表明,HVBR/EVM原位共混胶由于两相之间分散均匀,相畴尺寸小,两相相容性好;相比于二者传统机械共混硫化胶的阻尼性能,该原位共混硫化胶的有效阻尼温域增加明显,阻尼性能优异。Mo-based high vinyl polybutadiane rubber（HVBR） has vinyl-rich side gruups, the mole fraction of vinyl greater than 80% , dense vinyl side groups make segment＇s relaxation resistance increased, internal friclinn increased, the glass transiliun lemperature（Tg） of HVBR is abnut -2.5 ℃ , it is closer to room temperalure compared with other commonly used rubber damping materials. It has the potential to have excellent damping properties in the commonly used temperature range.
