"he substituents R3 and R4 are an aryl group and n and p are such that the molecular weight of the polymer is 600,000 g/mol, such as that sold under the name 761 by Rh??ne-Poulenc.The high molecular weight silicone polymer is preferably introduced into the composition in the form of a mixture with a liquid silicone, the viscosity of the liquid silicone being between 0.5 and 10,000 cSt, for example," .
