A 1,3-diketoamide functional monomer represented by the following formula (1):
wherein R and Y are independently selected from the group consisting of hydrogen, an alkyl group having from 1 to 10 carbon atoms, an aryl group having from 6 to 20 carbon atoms, and an aralkyl group having from 7 to 20 carbon atoms; and wherein X and Z are independently selected from the group consisting of an alkyl group having from 1 to 10 carbon atoms, an aryl group having from 6 to 20 carbon atoms, and an aralkyl group having from 7 to 20 carbon atoms. Also disclosed are emulsion, suspension, and solution polymers comprising residues from the 1,3-diketoamide functional monomer of formula 1 and, optionally, one or more additional ethylenically unsaturated monomers. Both latex and self-curing coating compositions described herein exhibit excellent hydrolytic stability, including increased retention of 1,3-diketo functionality.
一种由以下式(1)表示的1,3-二酮酰胺功能单体:其中R和Y分别独立地选自氢、具有1至10个碳原子的烷基基团、具有6至20个碳原子的芳基基团和具有7至20个碳原子的芳基基团所组成的群;以及X和Z分别独立地选自具有1至10个碳原子的烷基基团、具有6至20个碳原子的芳基基团和具有7至20个碳原子的芳基基团所组成的群。还披露了包含来自式1的1,3-二酮酰胺功能单体残基的乳液、悬浮液和溶液聚合物,以及可选地,一个或多个额外的乙烯基不饱和单体。本文描述的乳胶和自固化涂料组合物表现出出色的水解稳定性,包括增加的1,3-二酮功能保留。
