Title compds. (I) contained polyether blocks of mol. wt 300-10,000 and polyamide blocks of mol. wt. 10,000, bound together by ester linkages. I were prepd. by block copolymerization in which dibasic C36 acid was heated with aq. ethylene diamine and treated with propylene glycol. The polyether block made up 10-75wt.% of the total polymer and the amide ester bond ratio was 0.5:1 - 25:1.
