A highly polymerizable N-vinylcarboxylic acid amide having an N-1,3-butadienylcarboxylic acid amide content of 30 ppm or less, a process for producing the same, and a process for producing a homopolymer of N-vinylcarboxylic acid amide or a copolymer thereof with another copolymerizable monomer using the same. Also, a highly polymerizable N-vinyl carboxylic acid amide is produced by thermal cracking or catalytic cracking of N-(1-alkoxyethyl)carboxylic acid amide or ethylidenebiscarboxylic acid amide, wherein the N-vinylcarboxylic acid amide content of the N-(1-alkoxyethyl)carboxylic acid amide or ethylenebiscarboxylic acid amide is 10 wt % or less.
一种高度聚合性N-乙烯基羧酸酰胺,其N-1,3-丁二烯基羧酸酰胺含量为30ppm或更低,以及其生产方法和使用该方法生产N-乙烯基羧酸酰胺的同聚物或与另一可共聚单体的共聚物的方法。此外,一种高度聚合性的N-乙烯基羧酸酰胺可通过N-(1-烷氧基乙基)羧酸酰胺或乙烯基双羧酸酰胺的热裂解或催化裂解生产,其中N-(1-烷氧基乙基)羧酸酰胺或乙烯基双羧酸酰胺中的N-乙烯基羧酸酰胺含量为10wt%或更低。
