    摘要: A process for manufacturing an object by sintering comprises: (i) selecting a powder comprising a polymeric material having a repeat unit of formula -O-Ph-O-Ph-CO-Ph-, and a repeat unit of formula -O-Ph-Ph-O-Ph-CO-Ph- wherein Ph represents a phenylene moiety; and (ii) selectively sintering the powder to produce the object. The polymer used can be advantageously recycled and blended with virgin material to produce a blend which has very similar mechanical properties and crystallinity compared to the virgin material. In preferable embodiments the Ph- moiety is linked via para positions on the ring. Preferably the sintering is laser sintering.
