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. Phosphite YI 0 Irgafos 38 For different polyolefin polymers, the optimum particle sizes will differ slightly.

LI Free format text: It is also preferred if the UV-stabilisers are approved for use in polyolefins in contact with food. Ti, Zr or Hf. Additive analysis showed that the hydrolytic 338 was good no reaction, no hydrolysis of additives.

Polymer particles of a suitable size may be obtained by methods such as grinding, extruding and pelletising or simply synthesising polymer particles having a suitable particle size directly.

On the other hand, where the particle size is too small the powder will have poor flow characteristics and will not distribute evenly in the mould. Thus UV stabilisers which are soluble or partially soluble in the polymer e.

The rotation ratio was 9: Zinc stearate powder 9 g was added and the mixture blended for another five minutes. C at least one UV-stabiliser selected from [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]; [Poly 6-morpholino-s-triazine-2,4-diyl 2,2,6,6-tetramethyl-4 piperidyl imino hexamethylene 2,2,6,6-tetramethylpiperidyl imino ]; or [Poly 6- 1,1,3,3-tetramethylbutyl amino -1,3,5-triazine-2,4-diyl 2,2,6,6-tetramethylpiperidyl imino -1,6-hexanediyl 2,2,6,6-tetramethylpiperidyl imino ].

Irgafos[Tetrakis- 2,4-di- t -butylphenyl -4,4′-biphenylen-di-phosphonite] e. Jrgafos 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 lrgafos loaded with the catalyst, e. Melt flow rate of the powder did not change. Kind code of ref document: Environmental stress rupture resistance modifier and environmental stress rupture resistance-modified resin composition containing same.

The yellowness index of the resulting articles was measured. In this regard mention irgaos be made of the silver and boron compounds known in the art.

B1 Designated state s: A process as claimed in any one of claims 1 to 5 wherein said phenolic antioxidant is [Octadecyl 3- 3′,5′-di-tert. Where a co-catalyst is used, it may be used separately but more preferably it is also loaded onto the porous support material.

Preferably, the polymer particles has a mean polymer particle size e. What is required of such activators is that they should react with the metallocene or pyrazolyl complex to yield an organometallic cation and a non-coordinating anion see for example the discussion on non-coordinating anions J – in EP-A Asahi.

Besides the UV-stabilizer, the polymer irgaffos powder used according to the invention has materials capable of inhibiting degradation of the polyolefin polymer, i.

CY Free format text: A polymer moulding powder for rotational moulding obtainable by a process as claimed in any one of claims 1 to The polymer moulding powder should preferably comprise 0.

Pressgranulierte flame retardant composition, process for their preparation and their use. Rotational moulding using the moulding powder of the invention may be effected conventionally, e. Preferred UV stabilisers are high molecular weight hindered amine light stabilisers, e. Irgafos 38tris-nonylphenyl phosphite, [Tris 2,4-di- t -butylphenyl phosphite] e.
