POLY(ETHER-ESTER-AMIDE) ANTISTATIC COMPOSITIONS DERIVED FROM DIMR ACIDS

摘要

Durable block copolymer antistatic compositions comprised of polyether and polyamide blocks arranged linearly and joined together with linking ester groups have been prepared. The poly(ether-ester-amides) have molecular weights below the fiber-forming range and contain a specified amount of the polyether block and a definite ratio of amide to ester linkages. They are blended with polyesters, polyamides and other fiber-forming polymers to impart durable antistatic properties.
