摘要
在齐格勒 纳塔型催化体系中 ,用钕系或其他稀土作催化剂的聚丁二烯具有高顺式、高强度、高分子量的特点 ,适合于制造充油橡胶 ,而充油技术是充油橡胶生产的关键技术。本文介绍了钕系充油顺丁橡胶的 3种胶液充油工艺 :连续充油工艺、一次间断充油工艺和二次间断充油工艺。较全面地测试了钕系充油顺丁橡胶NdBR Oil的物理机械性能 ,并与国外镍系充油顺丁橡胶NiBR 31相比较。
Using Ziegler Natta catalytic system with Nd or other rare earth metals as catalyst,the polymer,such as cis 1,4 polybutadiene,possessed extremely high cis 1,4 unit content,usually more than 97%,high molecular weight,very good mechanical properties and strengths.It was hoped to manufacture excellent oil extended cis 1,4 polybutadiene rubber out of this polybutadiene with high molecular weight.The technology of oil extension is crucial in oil extended rubber production.Authors researched three kinds of oil extension process,and comprehensively tested the mechanical properties of neodymium catalyzed cis 1,4 polybutadiene oil extended rubber NdBR Oil.
