新型高分子改性剂的合成及含电气石功能聚合物的制备
|
摘要
采用丁二酸酐和乙酸乙烯酯进行共聚,制备了含有酸酐活性基团的高分子聚合物P(SA-VA);然后用该活性聚合物对电气石进行表面改性,制备了含电气石的功能聚合物。通过IR、XRD、SEM等对改性产物结构和形貌进行了表征。实验结果表明,P(SA-VA)的酸酐基团与电气石表面的羟基发生了反应,电气石粉体被成功地引入到共聚物中,得到了含电气石的功能聚合物。该功能聚合物具有优良的分散性和储存稳定性,且该含电气石的功能聚合物成膜后具有良好的力学性能和优异的负离子释放量、远红外辐射等性能。
In this paper,succinic anhydrides were copolymerized with vinyl acetate to get the p( SA-VA) with acid anhydride active group,and the surface modification of tourmaline was carried with p( SA-VA) as a modifier to prepare the tourmaline-containing functional polymer. The structure and morphology of the modified tourmaline and functional polymer were characterized by means of IR,XRD and SEM. The experimental results showed that the tourmaline was attached into the polymer by the reaction of the tourmaline surface hydroxyl groups with the anhydride group of P( SA-VA) to get tourmaline-containing functional copolymer,and it exhibited excellent dispersity and storage stability. And the membranes of the functional copolymer revealed good mechanical properties and excellent negative ion releasing,far infrared radiation performances.
