| 摘 要： | 选择甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、马来酸酐(MAH)为单体,以无规共聚的方式得到MMA-BA-MAH三元共聚物.然后与一定量的丙烯酸、四异丙氧基钛共同进行酯交换反应,得到大分子钛酸酯表面改性剂,用于纳米陶瓷粉体的表面改性.采用红外、核磁、热分析等手段对三元共聚物和大分子钛酸酯表面改性剂的结构进行表征,通过FTIR、NMR测试结果,证实了MMA-BA-MAH和大分子钛酸酯表面改性剂为预期的产物,热分析表明MAA-BA-MAH三元共聚物与四异丙氧基钛反应后,分解温度大大提高,最大分解速率时的温度为431℃,大分子钛酸酯表面改性剂的热稳定性好.以[η]定性表征共聚物的相对分子量,结果表明聚合物的相对分子量不是太大.
