Stabilisers are also vital in preventing degradation during the rotomoulding process and in the eventual rotomoulded article. Especially preferably the diluent is mineral oil or N,N-bis 2-hydroxyethyl dodecanamide.

Zinc Stearate powder was added and the mixture blended for another five minutes. An alternative way irafos producing the stabilized moulding powder might thus have seemed to be to simply blend the stabilizers with an olefin polymer particulate which already has the appropriate particle size for rotational moulding, e. A process as claimed in any one of claims 1 to 4 wherein said 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].

MC Free format text: Besides the stabilizer sthe moulding powder may contain with other additives, e. In this regard mention may be made of the silver and boron compounds known in the art.

TR Free format text: Melt flow rate of the powder did not change. Ref legal event code: Rotomoulded items prepared as in Example 3 were compared to a conventional rotomoulding powder RM from Borealis. Chimassorb and Chimassorb are available from Ciba Specialty Chemicals. ChimassorbPoly 6-morpholino-s-triazine-2,4-diyl 2,2,6,6-tetramethyl-4 piperidyl imino hexamethylene 2,2,6,6-tetramethylpiperidyl imino ] e. Suitable mixing apparatuses include Forberg, Idecon, and Lodige mixers.

Especially preferably 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]. 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.

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

NL Free format text: Viewed from another aspect the invention provides a polymer moulding powder for rotational moulding obtainable by a process as hereinbefore described. A polymer moulding powder for rotational moulding obtainable by a process as claimed in any one of claims 1 to The polyolefin polymer powder used in rotational moulding, e.

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. The mixture was blended for another five minutes.

Viewed from yet another aspect the invention provides a process for the preparation of a moulded polymer item, said process comprising:. Preferably the support material, if inorganic, is subjected to a heat treatment calcination before catalyst impregnation, e.

Rotational moulding is described for example by Oliveira et al.

AT Free format text: Preferably the metallocene contains at least one Cp group other than unsubstituted cyclopentadienyl, i. These products may be used in the food industry. LI Free format text: A process as claimed in any one of claims 1 to 6 wherein said at least one organic phosphite or phosphonite antioxidant is [Bis 2-methyl-4,6-bis 1,1-dimethylethyl phenyl phosphorous acid ethylester]. FI Free format text: A process as claimed in any one of claims 1 to 9 wherein said mixture comprises 0.

Polyethylene compositions, method of producing the same, articles made therefrom, and method making the same. Date of ref document: IE Free format text: Structures of these compounds are illustrated below.

The oven irgafks and oven curing time may be selected according to the melting characteristics of the polymer and the thickness of the item being produced.

A process as claimed in any one of claims 1 to 3 wherein said polyolefin polymers irafos are polyethylene or polypropylene homo or copolymer particles. Typical examples of suitable metallocenes include orgafos following: This however has until now resulted in unacceptable deposits of the UV-stabilizer on the surface of the mould used in rotational moulding. A process as claimed in any one of claims 1 to 5 wherein said phenolic antioxidant is [Octadecyl 3- 3′,5′-di-tert.

The mechanical property values determined are comparable with conventional rotomoulded articles showing that the process of the invention does not detrimentally affect mechanical properties.
