Abstract
"Process for obtaining mixtures of expandable thermoplastic materials, of fine particles", characterized in that at least one essentially halogen-free polymer or a mixed polymer of aromatic or cycloaliphatic vinyl compounds is intimately mixed with at least one polymer of vinyl chloride or vinylidene chloride or a mixed polymer of these monomers in an amount such that the chlorine content of the polymer mixture is from 8 to 2.5% by weight, preferably from 12 to 23% by weight, but that the weight ratio of a: b is not less than 60:40, and a gaseous or liquid blowing agent in an amount of 2 to 20% by weight, calculated on the mixture of the polymers.
