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.
BE Free format text: Polypropylene resin composition for rotational molding, manufacturing method the same and rotational molding product by using the same. DE DET3 en Preferably, the polymer particles has a mean polymer particle size e.
Thus besides or in addition to aluminoxanes, irgfaos cation complex forming catalyst activators may be used. Irgafos P-EPQ or [Phosphorous acid, cyclic butylethyl propandiol, 2,4,6-tri- t -butylphenyl ester] e. ES Ref irgacos event code: The catalyst with which the support material is impregnated may be any polymerization catalyst although preferably it will be a Ziegler Natta catalyst i. The polymer moulding powder should preferably comprise 0. Especially iegafos the UV stabiliser is [1,6-Hexanediamine, N, N’-bis 2,2,6,6-tetramethylpiperidinyl – polymer with 2,4,6-trichloro-1,3,5-triazine, reaction products with, N-butylbutanamine and N-butyl-2,2,6,6-tetramethylpiperidinamine].
The polymer moulding powder of the invention may be employed as the sole polymer rotomoulding component or may be combined with other polymers. Cyasorb is available iirgafos Cytec or from Everlight Taiwan where it is sold under the trade name Eversorb PT Free format text: Metallocene-produced very low density polyethylenes or irgafo low density polyethylenes as impact modifiers. GB Ref legal event code: The oven temperature and oven curing time may be selected according to the melting characteristics of the polymer and the thickness of the item being produced.
Irganox or [Pentaerythrityl-tetrakis 3- 3′,5′-di-tert. Melt flow rate and impact properties were comparable. The polymer powder onto which the mixture is deposited, e. It is also preferred if the UV-stabilisers are approved for use in polyolefins in contact with food.
Suitable mixing apparatuses include Forberg, Idecon, and Lodige mixers. Especially preferred is the organic phosphite antioxidant is Bis 2-methyl-4,6-bis 1,1-dimethylethyl phenyl phosphorous acid ethylester. LU Free format text: B2 Designated state s: SE Free format text: A mould is charged with polymer powder, closed and placed in an oven where it is irgaros so as iggafos distribute the polymer powder over the mould surface.
Year of fee payment: The UV stabilisers are [1,6-Hexanediamine, N, N’-bis 2,2,6,6-tetramethylpiperidinyl – polymer with 2,4,6-trichloro-1,3,5-triazine, reaction products with, N-butylbutanamine and N-butyl-2,2,6,6-tetramethylpiperidinamine] e. The moulding powder irgafoos was g giving a wall thickness of approximately 4 mm.
