▎ 摘  要

NOVELTY - Preparing maleic anhydride melt grafted polyolefin material comprises (i) adding 0.01-15 pts. wt. maleic anhydride, 0.01-10 pts. wt. graphene oxide directly into 100 pts. wt. polyolefin particle material or powder, mixing uniformly at normal temperature, adding the physical mixture into reaction device, (ii) providing 0.01-5 pts. wt. initiator, 0.01-10 pts. wt. styrene liquid, mixing uniformly, adding the mixture into the reaction device, and maintaining melt blending at a certain temperature. USE - The method is useful for preparing maleic anhydride melt grafted polyolefin material (claimed). ADVANTAGE - The material can inhibit polypropylene tertiary carbon chain radical degradation, crosslinked polyethylene secondary carbon chain radical, relatively high initiator content and will not cause large degradation or crosslinking, can control or regulate the degradation and crosslinking, has high graft rate of 3.1%, high molecular weight, and melting index of 3g/10 minute (230 degrees C, 2.16 kg).
