摘要： Disclosed are polymeric compositions with improved breakdown strength. The polymeric compositions contain a polyolefin and a voltage stabilizing agent. The voltage stabilizing agent contains a triazine. The triazine may include a substituent that enables keto-enol tautomerism, which provides the voltage stabilizing agent with additional energy dissipation capacity. The present polymeric compositions exhibit improved breakdown strength when applied as an insulating layer for power cable.

摘要： Silane-crosslinkable polymeric compositions comprising a polyolefin having hydrolyzable silane groups, an acidic silanol condensation catalyst, and a phenolic antioxidant. The phenolic antioxidant has a phenol-based moiety fused with a cyclic ether where the oxygen atom of the cyclic ether is located in the para position relative to the hydroxyl group of the phenol-based moiety. Such crosslinkable polymeric compositions can be employed in various articles of manufacture, such as in the wire and cable industry.
