Expandable vinylaromatic polymers and process for their preparation
CA 2462137 A1
Abstract
Expandable vinylaromatic polymers which comprise: a) a matrix obtained by polymerizing 50-100% by weight of one or more vinylaromatic monomers and 0.50%
by weight of a copolymerizable monomer; b) l-10% by weight, calculated with respect to the polymer (a), of an expanding agent englobed in the polymeric matrix; c) 0.05-25% by weight, calculated with respect to the polymer (a), of an inorganic filler homogeneously distributed in the polymeric matrix with a substantially spherical granulometry, an average diameter ranging from 0.01 to 100 ~m, a refraction index higher than l.6 and a white index, as defined in "Colour Index" (third edition published by the Society of Dyers and Colourists, 1982), equal to or lower than 22.
