Title:
THERMOPLASTIC ELASTOMER COMPOSITION AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/161981
Kind Code:
A1
Abstract:
Disclosed is a thermoplastic elastomer composition that has a continuous phase and a dispersed phase, with the continuous phase containing an epoxy-modified polyamide resin (A) and the dispersed phase containing a halogenated isoolefin-para-alkylstyrene copolymer rubber (B). Said thermoplastic elastomer composition is characterized by being obtained by melt-kneading the following at a temperature greater than or equal to the melting point of a polyamide resin (C): a halogenated isoolefin-para-alkylstyrene copolymer rubber (B); the aforementioned polyamide resin (C); and at least 0.05 mass parts and less than 3 mass parts, per 100 mass parts of the polyamide resin (C), of a polyfunctional epoxy compound (D), each molecule of which has at least two epoxy groups. The thermoplastic elastomer composition is further characterized in that the epoxy-modified polyamide resin (A) is generated by a reaction between the polyamide resin (C) and the polyfunctional epoxy compound (D) during the aforementioned melt-kneading.
