    • An acrylate or methacrylate functional copolymerizable monomer which serves as an adhesion for emulsion polymers is disclosed. This monomer is the adduct formed by reacting an aminoalkyl alkylene urea with about 0.9 up to about 1.5 molar proportions of a saturated monoepoxide to consume most or all of one of the two amino hydrogen atoms available, and then reacting with about 0.8 up to about 2.0 molar proportions of a monoisocyanate having a single acrylate or methacrylate group in the presence of at least 0.02%, based on the total weight of hte reactants present, of an inhibitor which retards the free-radical polymerization of ethylenic unsaturation, such as hydroquinone, and phenothiazine.
    • 公开了用作乳液聚合物的粘合剂的丙烯酸酯或甲基丙烯酸酯官能可共聚单体。 该单体是通过使氨基烷基亚烷基脲与约0.9至约1.5摩尔比例的饱和单环氧化物反应以消耗可用的两个氨基氢原子中的大多数或全部之一而形成的加合物,然后与约0.8至约2.0 在单体丙烯酸酯或甲基丙烯酸酯基团的摩尔比例,基于所存在的hTE反应物的总重量的至少0.02%,阻止烯键式不饱和键的自由基聚合如氢醌的抑制剂和 吩噻嗪。
