Abstract
Disclosed are elastomer-coated mineral particles which are characterized by being in the form of individual granules. The disclosure also relates to a process for preparing the said particles, the said process being characterized in that it consists of the following: a) Causing the mineral particles to react with at least one binding agent which includes at least one polyoxyethylenic sequence, and with at least one elastomer latex; b) Separation of the liquid phase from the particles; c) Drying of the said particles. The utilization of the said particles for the reinforcement of thermoplastic polymers and thermoplastic polymers reinforced with the mineral particles according to this invention are likewise disclosed.
