Abstract
A processable, stable, homogeneous blend is obtained by mechanically mixing a polydiorganosiloxane gum containing 0.2 to less than 1.5 mol percent silicon atoms having vinyl or allyl groups with an ethylene vinylacetate copolymer containing 8 to 35 weight percent copolymerized vinylacetate. The polymers are mixed at a shear rate greater than 10 sec.sup.-1, at a temperature between 170.degree. C. and 235.degree. C. and for a period of time sufficient to obtain at least 10 weight percent of the total blend of material which is insoluble in refluxing xylene.
