Claims
- 1. A thermoplastically processable composition comprising;
- (i) an elastomeric, block copolyetheresteretheramide consisting of recurring polyetheresteramide units A and polyetheramide units B in a ratio of units A to units B of 5:1 to 1:5, said units A and said units B being connected through ester and/or amide linkages, said units A being of Formula I ##STR5## there being 3 to 35 of said Formula I in each of said units A; said units B being of Formula II ##STR6## there being 3 to 35 of said Formula II in each of said units B; and wherein
- D represents a divalent radical which remains after the removal of the carboxylic groups from a polyamide with terminal carboxylic groups having an average molar mass of 700 to 10,000 g/mol,
- E is a divalent radical which remains after the removal of the hydroxyl groups from poly-(oxytetramethylene) with terminal hydroxyl groups having an average molar mass of 600 to 3,500 g/mol, and
- F is a divalent radical which remains after the removal of the amino group from poly-(oxy-1,2-propylene) with terminal amino groups having an average molar mass of 350 to 2500 g/mol, said copolyetheresteretheramide having a modulus of flexural elasticity of about 40 to about 700 N/mm.sup.2, and
- (ii) a polar copolyolefin.
- 2. The compound of claim 1 wherein said polar copolyolefin has a substituent selected from the group consisting of carboxyl, carboxylate, carboxylic acid anthydride, and mixtures thereof.
- 3. The method of producing shaped articles comprising extrusion, injection molding, coinjection welding, or blow molding the composition of claim 1.
