Relatively stable masterbatch compositions are provided comprising a matrix having a polysiloxane dispersed therein, prepared by admixing a solid or liquid matrix, a monomeric silane and a silane condensation catalyst with the result that the monomeric silane condenses to a polysiloxane which is dispersed throughout the matrix per se or as a reactant therein. The masterbatch composition can be admixed with alkylene-alkyl acrylate copolymers in the presence of an organic titanate, to produce water-curable compositions, containing water-curable, silane modified alkylene-alkyl acrylate copolymers, which are useful as extrudates about wires and cables providing protective coatings thereon. |
