甲基丙烯酸电气石酯-乙酸乙烯酯共聚物的制备与表征∗

摘要

In order to synthesize the tourmaline-containing functional copolymer,tourmaline methacylate was prepared by means of the surface organic modification of tourmaline powder with methacrylic anhydride,and then copolymerized with vinyl acetate to get a tourmaline methacylate-vinyl acetate copolymer,and the struc-tures of tourmaline methacylate and its copolymer were characterized via IR,XRD and SEM.Experimental re-sults show that tourmaline powder was successfully introduced into the copolymer,and exhibited an excellent dispersion in copolymer and storage stability.And the membrane of methacylate-vinyl acetate copolymer re-vealed a good mechanical properties and excellent negative ion release,far infrared radiation performances.%为了合成含电气石功能聚合物，采用甲基丙烯酸酐对电气石进行表面改性，在电气石表面引入双键，制备了甲基丙烯酸电气石酯，而后与乙酸乙烯酯进行共聚反应，合成了甲基丙烯酸电气石酯-乙酸乙烯酯共聚物。通过IR、XRD、SEM等手段对其进行结构和形貌表征，结果表明，电气石粉体成功引入到共聚物中，具有优良的分散性和储存稳定性。且甲基丙烯酸电气石酯-乙酸乙烯酯共聚物成膜后具有良好的力学性能和优异的负离子释放量、远红外辐射性等性能。
