HOMOGENEOUS, THERMOPLASTIC MIXTURES OF PROPYLENE-ETHYLENE / COPOLYMERISATEN AND LIQUID, SATURATED DIORGANOPOLYSILOXANS OF A SPECIFIC VISCOSITY RANGE

摘要

A homogeneous thermoplastic mixture comprising (A) from 85 to 99.5% by weight of a propylene-ethylene copolymer containing from 0.5 to 15% by weight of copolymerized ethylene units and having a melt index of from 1.0 to 30 g/min at 230 DEG C. and under a load of 5 kg; and (B) from 0.5 to 15% by weight of a saturated diorganopolysiloxane having a viscosity of from 30,000 to 80,000 Cst at 20 DEG C. The mixtures of the present invention are particularly suitable for the manufacture of elastic polypropylene based moulded articles which are dimensionally stable in heat.
