Abstract
The invention relates to reinforcing compositions for thermoplastic polymers which have improved anticaking and flow properties, which include an impact additive and a synergic combination including a micronized silica and at least one calcium salt. These compositions are very particularly suitable for the reinforcement of PVC.
