AMINOPALYAMIDE{13 ACRYLAMIDE{13 POLYALDEHYDE RESINS EMPLOYING AN ALPHA, BETA-UNSATURATED MONOBASIC CARBOXYLIC ACID OR ESTER TO MAKE THE AMINOPOLYAMIDE AND THEIR UTILITY AS WET AND DRY STRENGTHENING AGENTS IN PAPERMAKING

摘要

Disclosed are novel aminopolyamide-acrylamide-polyaldehyde resins useful in the paper making art to enhance the wet and dry strength of paper. The aminopolyamide results from the condensation of a polyalkylene polyamine with an alpha, beta-unsaturated monobasic carboxylic acid or ester.
