An assembly or apparatus for use in relation to an assembly, wherein said assembly is subjected to a temperature of less than &#x2212;50&#xb0; C. in use, wherein said assembly or apparatus includes a component which comprises a polymeric material (A) having a repeat unit of formula &#x2014;O-Ph-O-Ph-CO-Ph- (I) wherein Ph represents a phenylene moiety; and wherein said polymeric material (A) has a melt viscosity of at least 0.50 kNsm.

Polymeric materials

A method of fitting a compressed component, for example a pipe, in a receiver, for example a bore, comprises compressing a selected component which is made out of a polymeric material having a glass transition temperature of at least 100&#xb0; C., for example polyetheretherketone; arranging the compressed component in position within a receiver; and subjecting the compressed component to conditions, for example of temperature and/or pressure, whereby the compressed component expands.
