Polymers of n-3-hydroxyalkyl acrylamides and method of preparation
Abstract
Abstract N-3-HYDROALKYL ACRYLAMIDES, AND SUBSTITUTED DERIVATIVES THEREOF, ARE PREPARED BY (1) REDUCTION OF AN N-3OXOHYDROCARBON-SUBSTITUTED ACRYLAMIDE, (2) ADDITION OF AN ALCOHOL TO THE N-3-OXOHYDROCARBON-SUBSTITUTED ACRYLAMIDE, FOLLOWED BY HYDROGENATION OF THE CARBONYL GROUP AND ELIMINATION OF THE ALCOHOL, OR (3) HYDROLYSIS OF A 2-VINYL-5,6-DIHYDRO-1,3-OXAZINE. THE ACRYLAMIDES ARE USEFUL AS MONOMERS FOR CONVERSION TO POLYMERS (WHICH MAY ALSO BY PREPARED BY REDUCTION OF THE CORRESPONDING OXOHYDROCARBON-SUBSTITUTED ACRYLAMIDE POLYMERS) WITH A NUMBER OF INTERESTING PROPERTIES, INCLUDING UTILITY AS MEMBRANES FOR DESALINATION OF WATER BY HYPERFILTRATION. THE POLYMERS MAY BE CROSSLINKED BY THE ACTION OF SUCH REAGENTS AS DIISOCYANATES, DICARBOXYLIC ACID HALIDES, AND ALDEHYDES IN ACIDIC SOLUTION. D R A W I N G
