Abstract
A polyamide co-polymer polyol made by the reaction of a dicarboxylic acid diester with a diamine in the presence of a polyether polyol is described. The nylon formed should be present in the polyol in an amount of from 1 to 30 wt. %. The polyether polyol may have a molecular weight of about 2,000 to 8,000. This polyamide co-polymer polyol may be used in the manufacture of elastomers and flexible polyurethane foams which are characterized by good load bearing properties.
