Thus besides or in addition to aluminoxanes, other cation complex forming catalyst activators may be used.
EPB2 – Process for addition of additives to polymer particles – Google Patents
It has now been surprisingly found that a particular blend of additives may be employed in melt additivation without unacceptable deposits of the UV-stabilizer on the surface of the mould used in rotational moulding being formed.
Particularly preferably the metallocene irgfos a bridged bis-indenyl metallocene. Especially preferably the diluent is mineral oil or N,N-bis 2-hydroxyethyl dodecanamide. Country of ref document: Kind code of ref document: Many metallocene catalysts are known, e. R Ref document number: A process as claimed in any one of claims 1 to 9 wherein said mixture comprises 0.
Cyasorb is available from Cytec or from Everlight Taiwan where it is sold under the trade name Eversorb For different polyolefin polymers, the optimum particle sizes will differ slightly. FG2A Ref document number: GR Free format text: Where a co-catalyst is used, it may be used separately but more preferably it is also loaded onto the porous support material.
What is required of such activators is that they should react with the metallocene or irgafoss 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.
The YI values for the rotomoulded articles made in Examples 5 and 6 are lower than those associated with conventional rotomoulded articles. 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.
Ref legal event code: Polyolefinepoedersamenstellingen, in particular polyethylene powder compositions itgafos improved adhesion, and to manufacture thereof, and articles of manufacture. B1 Designated state s: BE Free irgaffos text: Polyethylene compositions, method of producing the same, articles made therefrom, and method irrgafos the same.
A process as claimed in any one of claims 1 to 10 wherein all the components of said mixture are approved for contact with food. Use of a mixture containing phenoxy resin as an additive for a thermoplastic polymer to reduce its diffusion coefficient.
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]. The polymer moulding powder of the invention may be employed as the sole polymer rotomoulding component or may be combined with other polymers. Thus, viewed from one aspect the invention provides a process for the preparation of a polymer moulding powder for rotational moulding, said process comprising:.
B2 Designated state s: Date of ref document: This choice of particle size and uniformity ensures uniformity in the resulting rotationally moulded product. LU Free format text: A process for the preparation of a polymer moulding powder for rotational moulding, said process comprising: A at least one phenolic antioxidant.
LI Free format text: 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. Irganox and Irganox are available from Ciba Specialty Chemicals.
