Abstract

Se describe una composicion termoplástica consistente en una mezcla resinosa de un poliuretano termoplástico basado en poliéter-poliol que tiene una dureza Shore A no mayor de 90 y una goma de polibutadieno injertado. En la composicion inventiva, la cantidad relativa en la mezcla de poliuretano predomina sobre la cantidad de goma de polibutadieno injertado. La composicion es especialmente adecuada para la preparacion, por termoformacion, de artículos que tiene bajo brillo y que están idénticamente caracterizados por su "suave toque". También se describe un método para reducir el brillo a 60 grados de un artículo termoformado a partir de una composicion termoplástica que contiene una mezcla de poliuretano termoplástico y goma de polibutadieno injertado.
