Abstract:
A process for the preparation of a moulded polymer item, said process comprising obtaining a polymer moulding powder having a mean particle size of 1 to 2000 &mgr;m comprising an admixture of UV-stabilizer-loaded polymer particles and non-UV-stabilizer-loaded polyolefin polymer particles, loading said powder into a mould, heating and rotating said mould to melt said powder, cooling said mould, and releasing said moulded polymer item from said mould, wherein said UV-stabilizer loaded and UV-stabilizer unloaded particles are present in a weight ratio of from 0.5:99.5 to 1:10, and said UV-stabiliser loaded polymer particles are formed from homopolymers or copolymers of &agr;-olefins.
