Polyolefins are very widely used, both as elastomers and rigid thermoplastics. One major advantage of ethylene/α-olefin/divinylbenzene(DVB) terpolymer is the existence of many pending styrene groups along backbone, which are very reactive in many chemical reactions. Prior to the experiment, Poly(ethylene-ter-hexen-ter-divinylbenzene)(PEHV) terpolymers containing divinylbenzene side group prepared by a metallocene copolymerization. In this study, We synthesized PEHV-g-P(t-BS) and PEHV-g-PS graft copolymer having tert-butylstyrene or styrene hard segment side chains using anionic graft-from polymerization. The result indicated that this process produced a new well-defined functionalized graft-type polyolefin-based TPE with high Tg hard block. |
