摘要
以二异丙醇胺(DIPA)及酸酐为原料合成了含有一个羧基、两个羟基的AB2型单体,采用AB2型单体自缩聚的方法合成了超支化聚酰胺酯,然后用甲基丙烯酸对超支化聚酰胺酯的端基功能改性。然后将超支化单体与马来酸酐、甲基丙烯酸共聚合成阻垢分散剂。
A novel AB2-type monomer containing a single carboxylic group and two hydroxylic groups was obtained by the reaction of diisopropanolamine（DIPA） and carboxylic anhydride.Based upon the efficient esterification,the kinds of hyperbranched polyesteramides were developed from AB2-type monomer.Then the polymer was modified by methacrylic acid on the end groups.Then the hyperbranched monomer was synthesized with acrylic acid and maleic anhydride copolymer scale inhibitor.
