Abstract:
    Coherent thermoplastic aggregates with very high content of pulverized mineral materials, composed of the said materials, of polyolefin polymers and/or copolymers, and possibly also of various familiar adjuvants, characterized by the fact that, in order for them to have both a volumetric mass close to or at most equal to the theoretical volumetric mass of the pulverized mineral substances entering into their composition and an excellent compatibility with redispersion polymers, the polymers and/or copolymers entering into the composition of the said aggregates in presence of a fluidizing agent are chosen within the group of thermoplastics with melting and/or softening point at least equal to 60 DEG C. and index of fluidity at least 50 (measured according to the standard ASTM D 1238) of the polyolefin type, other than those containing a polar monomer.
