摘要:
采用自制的负载钛系催化剂催化丁烯-1与己烯-1进行本体聚合制备了丁烯基弹性体，开展了聚合工艺优化研究，通过核磁共振波谱和差示扫描量热表征了共聚物的结构，考察了共聚物的物理机械性能。结果表明，最佳聚合工艺条件：n（单体）/n（催化剂）为20 000~25 000，n（三乙基铝）/n（负载钛系催化剂）为250~300，聚合温度为45 ℃，聚合时间为4 h，氢气压力为0.10~0.15 MPa；共聚物含有丁烯-1与己烯-1的无规共聚结构且无固定熔点；随着共聚单体己烯-1用量的增加，共聚物的拉伸强度和弹性模量均减小，当加入己烯-1质量分数为20%时，共聚物的断裂标称应变达到534%。
Abstract:
Butene-based elastomers were prepared by bulk polymerization of butene-1 and he-xene-1 using self-made supported titanium catalyst, and the optimization of polymerization process was studied. The structure of the copolymers was characterized by nuclear magnetic resonance spectrometer and differential scanning calorimetry, and the physical and mechanical properties of the copolymers were investigated. The results showed that the optimum polymerization conditions were as follow：n(monomers)/n(catalyst) was in range of 20 000 to 25 000, n(triethylaluminum)/n(supported titanium catalyst) was in range of 250 to 300, reaction tem-perature was 45 ℃, reaction time was 4 h，hydrogen pressure was in range of 0.10 to 0.15 MPa. The copolymer contained a random copolymer structure of butene-1 and hexene-1. The copolymer had no fixed melting point. The tensile strength and elastic modulus of the copolymer decreased with the increase of the amount of hexene-1, and the nominal fracture strain of the copolymer reached 534% when the mass fraction of hexene-1 was 20%.
