摘要:
Compositions of relatively stable polymers of an olefinic monomer and an unsaturated silane; and an organo titanate, wherein a readily hydrolyzable group of the titanate ester exchanges with one ester group of the silane moieties of the stable polymers to provide readily water-curable polymers which are useful as extrudates about wires and cables.
摘要:
Reaction products of a difunctional compound and an organotitanate, process for the preparation thereof and the use of these reaction products as crosslinking agents in the preparation of cured products based on alkylene-alkyl acrylate copolymers. The cured products are especially useful as protective coatings about wires and cables.
摘要:
The disclosure of this application is directed to a composition, devoid of added mineral filler, comprising an ethylene polymer and an organo titanate as a water treeing inhibitor. The compositions can be extruded about electrical conductors providing insulation thereon which is resistant to deterioration in the presence of moisture and an electrical field.
