Abstract
Abstract The disclosure of this application is directed to a polysiloxane, having combined therein an organo titanate, which can be used in the production of silane modified alkylene-alkyl acrylate copolymers. The silane modified copolymers can be extruded about electrical conductors to provide insulation thereon characterized by improved surface characteristics.
