摘　　要：聚烯烃热塑性弹性体(POE)的非极性限制了它的进一步应用,为了扩大其使用领域,对POE官能化引起关注。将POE作为接枝机体树脂,利用其支化度比较高、容易形成接枝点来获得较高的接枝率;由于其侧链相对较大,有可能降低大分子自由基之间碰撞的几率,从而减轻凝胶化程度,得到具有良好流动性的接枝树脂。本文综述了聚烯烃热塑性弹性体POE官能化几种方法,包括在有机过氧化物引发剂存在下的熔融接枝法、裂解引发接枝、机械力引发接枝、复合引发接枝等等,并对其产物的应用进行概括。The functionalization of polyolefin elastomer is more and more attended due to its limited application. In the grafting reaction, the high graft yield is gained when POE is the grafting polymer, by using its structural properties such as higher branched degree and bigger side-chain. A few methods of functionalization of polyolefin elastomer are reviewed, including melt-grafting initiated by peroxide,cracking initiation,mechanical force initiation,the compounded initiation. In addition,the application of graft polymer is also summarized in this paper.
