Claims
- 1. A thermoplastic elastomer composition having a flexural modulus as defined in ASTM D790 of from 500 to 15,000 kg/cm.sup.2, which is obtained by:
- melt kneading a mixture comprising: p2 (A) from 20 to 58 parts by weight of a polyamide resin and
- (B) from 42 to 80 parts by weight of an ethylene copolymer comprising:
- (a) from 40 to 90% by weight of an ethylene unit,
- (b) from 5-60% by weight of an .alpha.,.beta.-unsaturated carboxylic acid alkyl ester unit, and
- (c) from 0.3 to 10% by weight of a maleic anhydride unit; and
- further melt kneading said mixture with
- (C) from 0.01 to 20 parts by weight, based on 100 parts by weight of the sum of the polyamide resin (A) and the ethylene copolymer (B), of a compound selected from a group consisting of an aliphatic diamine carbamate, an aliphatic polyamine, an alicyclic polyamine, and an aromatic amine.
- 2. A thermoplastic elastomer composition as in claim 1, wherein the ethylene copolymer (B) comprises (a) from 65 to 90% by weight of an ethylene unit, (b) from 10 to 35% by weight of an .alpha.,.beta.-unsaturated carboxylic acid alkyl ester unit, and (c) from 1 to 5% by weight of a maleic anhydride unit or a partially ionized maleic anhydride unit.
- 3. A thermoplastic elastomer composition as in claim 1, wherein said compound (C) is an aliphatic diamine carbamate.
- 4. A thermoplastic elastomer composition as in claim 3, wherein the said compound (C) is hexamethylenediamine carbamate.
