THERMAL GRAFTS OF POLYAMIDES WITH PENDANT CARBOXYLIC ACID GROUPS, METHODS FOR PRODUCING THE SAME, COMPOSITIONS CONTAINING THE SAME, AND METHODS OF USING THE SAME

摘要

Heating an intimate mixture of: (a) a polyamide which contains pendant carboxylic acid groups; and (b) a compound which contains an amino group efficiently affords graft polymers with a high graft density. Such graft polymers are particularly useful as additives for cementitious compositions.
