摘　　要：在模试装置上合成出轮胎用低顺式聚丁二烯橡胶(LCBR)。测试结果表明:分子参数稳定可控,硫化胶物性指标优于国外样和燕山BR9000;磨耗、撕裂强度、弹性和曲挠龟裂与国外样基本相当,加工性能好,能够满足全钢载重子午胎的性能需要。Low cis-polybutadiene rubber (LCBR) was synthesized in experiment.The results showed that molecular feathers were steady and controllable,physical properties of cured rubber were superior to external product and YanShan BR9000,abrasion,tear strength,elasticity and flex crack were equal to external product,LCBR had good processing behavior,and could meet the needs for steel-belted radial tyre.
