摘　　要：采用负载钛催化体系合成了全同聚1-丁烯及1-丁烯与丙烯共聚物(简称共聚物)。研究了室温时共聚物的晶型转变过程及其力学性能。结果表明,共聚物的结晶度要小于全同聚1-丁烯的;共聚物的力学性能有所降低;共聚物的球晶较全同聚1-丁烯的小,且不如后者的球晶完善;共聚物的晶型转变速率明显快于全同聚1-丁烯的。The isotactic poly（1-butene） and 1-butane-co-propylene copolymer were prepared with catalyst system consisting of supported titanium. The mechanical properties and crystal transformation were investigated at room temperature. The results indicate that erystallinity of the copolymer is less than that of the isotactic poly（1-butene） and mechanical properties of the copolymer is decreased slightly, spherulites of the copolymer is smaller than that of isotactie poly（1-butene） and is accompanied by the imperfectness of the spherulites. The crystal transformation rate of the copolymer is obviously faster than that of isotactic poly（1-butene）.
