Patent ID: 8648145

Claim:
Thermoplastic elastomer vulcanizate comprising: a first phase (A) based on at least one thermoplastic polymer; a second phase (B) based on at least one two-component (B1 and B2) liquid silicone elastomer crosslinked by hydrosilylation; and a system (C) for compatibilizing these phases together, wherein said system comprises: at least one polymer (C1) chosen from the group consisting of grafted polyolefins, terpolymers containing poly(vinylaromatic/conjugated diene/methyl methacrylate) blocks, terpolymers containing poly(methyl methacrylate/alkyl acrylate/methyl methacrylate) blocks, ethylene/alkyl(meth)acrylate/acrylic acid terpolymers and polymers resulting from at least one glycidyl ester such as ethylene/(meth)acrylate/glycidyl (meth)acrylate terpolymers; and a polyorganosiloxane (C2) with SiH functional group(s), and in that said elastomer forms a homogeneous dispersion of said first and second phases obtained by reactive extrusion with at least the second phase which is continuous therein.
