Disclosed is a composition including a carbonyl-substituted alkene including a dicarbonyl compound having an alkylene group between the carbonyl groups. At least one carbonyl group of the dicarbonyl compound includes an amide group. Another carbonyl group may be a keto group or carbonyl group including an amide group. The composition may include methylene keto malonamides and methylene dimalonamides. Also disclosed are polymers containing these compositions. These polymers may be a copolymer formed with the composition and another 1,1-disubstituted alkene. The polymers may contain multi-functional monomers and/or crosslinkers. The present teachings disclose combining, to form a mixture, a dicarbonyl compound having an alkylene group between the carbonyl groups, formalin or a formaldehyde precursor, and an acid catalyst. The process may form methylene dimalonamides, methylene keto malonamides, for example.
揭示了一种包括含有碳酰基取代烯烃的组合物,其中包括具有碳酰基之间具有烷基链的二碳酰基化合物。该二碳酰基化合物的至少一个碳酰基包括酰胺基团。另一个碳酰基可能是酮基或包括酰胺基团的碳酰基。该组合物可能包括亚甲基酮基马隆酰胺和亚甲基二马隆酰胺。还揭示了含有这些组合物的聚合物。这些聚合物可能是与该组合物和另一种1,1-二取代烯烃形成的共聚物。这些聚合物可能含有多功能单体和/或
交联剂。目前的教导揭示了将具有碳酰基之间具有烷基链的二碳酰基化合物、
甲醛或
甲醛前体和酸催化剂结合形成混合物的方法。该过程可能形成亚甲基二马隆酰胺、亚甲基酮基马隆酰胺等。
