Abstract

The invention pertains to a process for cryogenic milling mixtures of (per)fluoroelastomers and semicrystalline thermoplastic VDF polymers, and to free-flowing micronized pellets obtainable therefrom, said micronized pellets advantageously yielding, after extrusion and compounding, excellent mechanical properties, even improved over those of base fluoroelastomer matrix.
