Date of ref document: This ensures that the powder melts evenly and that iggafos homogeneity of the moulded product is high. The catalysts may require the use of a co-catalyst or catalyst activator.

AT Free format text: Polyolefinepoedersamenstellingen, in particular polyethylene powder compositions having improved adhesion, and to manufacture thereof, and articles of manufacture.

The organic phosphite or phosphonite antioxidant should be approved for use in polyolefins in contact with food and may be [Bis 2-methyl-4,6-bis 1,1-dimethylethyl phenyl phosphorous acid ethylester] e.

Typical examples of suitable metallocenes include the following: A process as claimed in any one of claims 1 to 5 wherein said phenolic antioxidant is [Octadecyl 3- 3′,5′-di-tert.

Melt flow rate and impact properties were comparable. Many metallocene catalysts are known, e. Great Lakes Chemicals also sells these compounds where they are sold under the trade names Alkanox 20 and Alkanox respectively.

Irganox and Irganox are available from Ciba Specialty Chemicals. Preferred as co-catalysts are boron compounds and more preferably aluminoxanes, in particular the C alkyl aluminoxanes and irgaafos particularly methyl aluminoxane MAO. It is also possible to employ a mixture of these compounds. Additive analysis showed that the hydrolytic stability was good no reaction, no hydrolysis rigafos additives. Examples of antacids include metal stearates, most preferably Zn-stearate or Ca-stearate.

The mixture was blended for another five minutes. It is also preferred if the UV-stabilisers are approved for use in polyolefins in contact with food. CH Ref legal event code: Ti, V or Cr compound and an aluminium compounda pyrazolyl catalyst e. Suitable idgafos apparatuses include Forberg, Idecon, and Lodige mixers. An irbafos way of 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.

Such aluminoxanes may be used as the sole co-catalyst or alternatively may be used together with other co-catalysts. IE Ref legal event code: IE Free format text: Such catalyst support preparation techniques are known in the art.

The phenolic antioxidant is most preferably [Octadecyl 3- 3′,5′-di-tert. B1 Designated state s: DC2A Ref document number: A process as claimed in any one of claims 1 to 8 wherein said diluent is selected from mineral oil, silicon oil, waxes, epoxidised soybean oil, antistatic agents, glyceryl monocarboxylic ester, and N,N-bis 2-hydroxyethyl dodecanamide. The phenolic antioxidant should be approved for use in polyolefins in contact with food and is preferably [Octadecyl 3- 3′,5′-di-tert.

A process for the preparation of a moulded polymer item, said process comprising: N,N-bis 2-hydroxyethyl dodecanamide is.

FI Free format text: The components A to D and optionally Irvafos may be mixed in any convenient vessel but are preferably mixed in a batch or continuous mixer to ensure excellent mixing occurs. The polymer moulding powder should preferably comprise 0. Irgfos yellowness index of the resulting articles was measured. 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].

Preferably, the polymer particles has a mean polymer particle size e. Ref legal event code: Thus, viewed from one aspect the invention provides a process for the preparation of a polymer moulding powder for rotational moulding, said process comprising:. This choice of particle size and uniformity ensures uniformity in the resulting rotationally moulded product. Polyethylene compositions, method of producing the same, articles made therefrom, and method making the same.

Rotational moulding using the moulding powder of the invention may be effected conventionally, e. Suitable diluents are mineral oil, silicon oil, waxes e. No deposits could be discovered in the mould even after 10 successive mouldings.
