Abstract
Coherent thermoplastic aggregates with very high content of pulverulent mineral materials, said aggregates comprised of the said mineral materials, further of polyolefin polymers and/or copolymers, and possibly additionally of miscellaneous known additives; characterized in that, with the aim of achieving a density near to or at most equal to the theoretical density of the pulverulent mineral materials entering into their composition, while still having excellent compatibility with the polymers of redispersion, i.e., the polymers into which the subject aggregates are to be mixed, the interparticle voids between the grains of the mineral materials, which grains are basically in contact with each other, are at most filled--in the presence of a fluidifacient agent--by at least one polyolefin polymer and/or copolymer having a fusion temperature and/or softening temperature at least equal to 60.degree. C., and having a fluidity index (ASTM 1238) of at least 50.
