An electrical connector for supplying power to electrical equipment includes a first connector part with an electrically conductive pin and an insulating layer, and a second connector part with a socket. The electrically conductive pin in the first connector part is configured for engagement with the socket of the second connector part and for transmitting power or data or both through the electrically conductive pin to the socket part. The insulating layer is in intimate contact with and at least partially covering the electrically conductive pin and electrically insulates the pin from a body of the first connector part of the connector. The insulating layer includes a polymeric material having a repeat unit of formula: —O-Ph-Ph-O-Ph-CO-Ph- (I) and a repeat unit of formula —O-Ph-Ph-O-Ph-SO2-Ph-Ph-SO2-Ph- (II) wherein Ph represents a phenylene moiety; and wherein the repeat units I and II are in the relative molar proportions 95:5 to 80:20.

This invention relates to copolymers which consist essentially of [-ether-phenyl-ether-phenyl-carbonyl-phenyl-]and [ether-phenyl-phenyl-ether-phenyl-carbonyl-phenyl-] repeat units, as well as end units, which have reduced melting temperature (Tm) compared to prior art copolymers including such repeat units. The copolymers of the invention exhibit crystallinity and have similar glass transition temperatures to the prior art polymers.
