However it has been found that polyolefin polymer particles of appropriate size for preparation of the moulding powder may readily be prepared using supported catalysts, in particular catalysts comprising porous particulates loaded with the catalyst, e. The use of N,N-bis 2-hydroxyethyl dodecanamide may also improve surface finish.

A process as claimed in claim 1 or 2 wherein said at least one organic phosphite or phosphonite antioxidant is selected from [Bis 2-methyl-4,6-bis 1,1-dimethylethyl phenyl phosphorous acid ethylester], [Tris 2,4-di- t -butylphenyl phosphite], tris-nonylphenyl phosphate, [Tetrakis- 2,4-di- t -butylphenyl -4,4′-biphenylen-di-phosphonite] or [Phosphorous acid- cyclic butylethyl propandiol, 2,4,6-tri- t -butylphenyl ester].

The mixture was blended for another five irgados. Rotational moulding is a polymer moulding technique which is particularly suitable for the production of large polymer products, especially containers.

Suitable diluents are mineral oil, silicon oil, waxes e.

The rotation ratio was 9: Stabilisers are also vital in preventing degradation during the rotomoulding process and in the eventual rotomoulded article. Influence of UV stabiliser on properties of rotomoulded article. These are linear or cyclic oligomers having up to 40, preferably 3 to 20, -[Al R” O]- repeat units where R” is hydrogen, C alkyl preferably methyl or C aryl or mixtures thereof.

DE Ref legal event code: In this event it is preferred to allow the catalyst and the co-catalyst to react in a liquid phase and to load the reaction product onto the support.
