Abstract
La presente invención se refiere a un composito de poliuretano termoplástico que comprende nanopartículas funcionalizadas incorporadas en una matriz de poliuretano y su proceso de síntesis. El proceso comprende fundir un diisocianato en un reactor en una atmósfera con gas inerte; adicionar un macrodiol hasta obtener un pre-polímero y adicionar un extensor de cadena. Las nanopartículas funcionalizadas pueden ser incorporadas en el diisocianato, en el macrodiol o en el extensor de cadena.The present invention relates to a thermoplastic polyurethane composition comprising functionalized nanoparticles incorporated in a polyurethane matrix and its synthesis process. The process comprises melting a diisocyanate in a reactor in an atmosphere with inert gas; add a macrodiol until a prepolymer is obtained and add a chain extender. The functionalized nanoparticles can be incorporated in the diisocyanate, in the macrodiol or in the chain extender.
