Abstract
A polyaryletherketone, PAEK, in the form of particles is a copolymer with at least 95 mole % repeat units of formula I, and repeat units of formula II, and a molar ratio I:II from 55:45 to 80:20. The PAEK has a melt viscosity, MV, from 0.35 to 0.55 kNsmat 1000 s. The PAEK is of use in formation of components having high elongation at break when formed by selective sintering and melt-bonding of sequentially deposited layers of powder comprising the PAEK particles. Also provided are processes for making the PAEK particles, powders including them and their use and methods of their use in component formation.
