  The invention relates to a process for the preparation of .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, novel .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, a process for the polymerization of these novel .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, including the polymers, and the use of these polymers as sedimentation, flocculating, dewatering and retention aids, as additives for mineral oils, and as ion exchangers. The .alpha., .beta.-unsaturated N-substituted carboxylic acid amides are prepared by transamidation of .beta.-hydroxy or .beta.-alkoxy carboxylic acid amides with primary amines and heating of the N-substituted .beta.-hydroxy or .beta.-alkoxy carboxylic acid amides obtained as intermediate products in the vapor phase in the presence of catalysts. Primary amines are preferably used in the conversion which have no hydrogen beta to the amino group. These .alpha.,.beta.-unsaturated carboxylic acid amides may be neutralized and/or quaternized and polymerized by processes which as such are known alone or with other comonomers, and preferably acrylic or methacrylic acid derivatives such as acrylamide, to give cationic polymers. These polymers are suited for use as flocculating and sedimentation aids, as dewatering and retention aids in papermaking, as additives for mineral oils, and as ion exchangers.

  该发明涉及一种制备α，β-不饱和N-取代羧酸酰胺的过程，新型α，β-不饱和N-取代羧酸酰胺，一种用于这些新型α，β-不饱和N-取代羧酸酰胺聚合的过程，包括聚合物，并将这些聚合物用作沉淀，絮凝，脱水和保留助剂，矿物油添加剂和离子交换剂。α，β-不饱和N-取代羧酸酰胺是通过β-羟基或β-烷氧基羧酸酰胺与一级胺的转酰胺化反应制备的，并在催化剂存在下在蒸汽相中加热所得的N-取代β-羟基或β-烷氧基羧酸酰胺中间体产品。在转化中最好使用没有氨基团β位氢的一级胺。这些α，β-不饱和羧酸酰胺可以被中和和/或季铵化，并通过已知的聚合或与其他共聚单体一起聚合的过程聚合，最好是丙烯酰胺或甲基丙烯酸衍生物，例如丙烯酰胺，以形成阳离子聚合物。这些聚合物适用于作为絮凝和沉淀助剂，造纸中的脱水和保留助剂，矿物油添加剂和离子交换剂。
