Abstract
A component comprises a first part and a second part, wherein said second part is in contact with said first part, wherein: (i) said first part comprises a first polymer which is semi-crystalline and includes phenylene moieties, carbonyl moieties and ether moieties; (ii) said second part comprises a second polymer which is semi-crystalline and includes phenylene moieties, carbonyl moieties and ether moieties; (iii) the melting temperature (Tm) of the second polymer is less than the melting temperature (Tm) of the first polymer. In a preferred embodiment, said first polymer is polyetheretherketone and said second polymer is a copolymer having a repeat unit of formula VIII and a repeat unit of formula IX.
