Abstract
A cross-linkable polymer composition containing a cross-linkable polymer having at least one hydrolysable silane group, a silanol condensation catalyst and a polybutadiene. The composition provides a cross-linked polymer having good water tree resistance properties, for use as insulation in electrical cables.
Claims20
An improved cross-linkable polymer composition containing a cross-linkable polymer having at least one hydrolysable silane group and at least one silanol condensation catalyst characterized in that said composition further comprises a polybutadiene.
A process for producing a cross-linked polymer comprising the steps of:
- treating a composition comprising a cross-linkable polymer having at least one hydrolyzable silane group, at least one silanol condensation catalyst and a polybutadiene, under cross-linking conditions to produce said cross-linked polymer.
A coated substrate having enhanced resistance to water tree formation comprising a substrate which is coated with a composition comprising a cross-linkable polymer having at least one hydrolyzable silane group, at least one silanol condensation catalyst, and a polybutadiene.
