摘　　要：采用甲基丙烯酸缩水甘油酯(GMA)为液体聚异丁烯(LPIB)的接枝物,并用苯乙烯为其共聚单体,利用溶剂热法合成了甲基丙烯酸缩水甘油酯接枝液体聚异丁烯(LPIB-g-GMA)。研究了LPIB-g-GMA对不饱和聚酯树脂(UPR)力学性能及其它性能的影响。结果表明,随着LPIB-g-GMA含量的增加,UPR/LPIB-g-GMA的冲击强度先升高后降低,并在LPIB-g-GMA质量分数为4%时达到最大,约为纯UPR冲击强度的1.7倍。LPIB-g-GMA的加入对UPR的拉伸性能及热性能影响不大,是UPR良好的增韧刘。By using glycidyl methacrylate （GMA） as the graft polymer, styrene as the comonomer, GMA grafted liquid polyisobutylene （ LPIB-g-GMA ） was synthesized through solvothermal method, and its effect on unsaturated polyester resin （ UPR ） was studied.The results indicated that the impact strength of UPR/LPIB-g-GMA exhibited a rise and then decrease trend with the increasing of LPIB-g-GMA. The impact strength of UPR / LPIB-g-GMA reached the maximum, about 1.7 times of that of pure UPR, when the content of LPIB-g-GMA was 4wt%, while tensile property and thermal property changed a little.
