Abstract

La presente invencion describe polimeros vinilaromaticos expandibles que comprenden: a) una matriz obtenida por medio de polimerizacion de 50-100% en peso de uno o mas monomeros vinilaromaticos y 0.50% en peso de un monomero copolimerizable; b) 1-10% en peso, calculado con respecto al polimero (a), de un agente de expansion englobado en la matriz polimerica; c) 0.05-25% en peso, calculado con respecto al polimero (a), de un rellenador inorganico homogeneamente distribuido en la matriz polimerica con una granulometria sustancialmente esferica, un diametro promedio en el intervalo de desde 0.01 a 100 ??m, un indice de refraccion mayor que 1.6 y un indice blanco, como esta definido en el "Indice de Color" (tercera edicion publicada por Society of Dyers and Colourists, 1982), igual a o menor que 22.
