The invention comprises a homogeneous liquid mixture of (a) a half ester of an organic polyol characterized by the following empirical formula:
wherein n is a number having an average value of about 1.8 to less than about 4, m is equal to the free valence of R less the average value of n, R is the hydroxyl-free residue of an organic polyol which contained from 2 to 4, inclusive, hydroxyl groups, OH, in formula (I), (b) maleic anhydride, (c) an ethylenically unsaturated monomer which forms a liquid homogeneous mixture with and is copolymerizable with the half ester and maleic anhydride, and (d) a basic compound.
本发明包括一种均质液体混合物,其中(a)有机多元醇的半酯,其特征为以下经验 式:
其中 n 是一个平均值约为 1.8 至小于约 4 的数字,m 等于 R 的游离价减去 n 的平均值,R 是有机多元醇的无羟基残余物,在式 (I) 中含有 2 至 4 个羟基,OH,(b) 顺丁烯二酸酐,(c) 乙烯基不饱和单体,它与半酯和顺丁烯二酸酐形成液体均相混合物并可共聚,和 (d) 碱性化合物。
