  • Publication number: 20080308296
    Abstract: The invention relates to a polymer composition, comprising (a) a polyolefin base resin which comprises at least (a1) a first olefin homo- or copolymer fraction, and (a2) a second olefin homo- or copolymer fraction, wherein the weight average molecular weight of the first fraction is lower than the weight average molecular weight of the second fraction, and (b) at least one additive selected from a polar copolymer; a low density polyethylene; an ether and/or ester group containing additive selected from the group consisting of polyethylene glycol, a glycerol ester compound, polypropylene glycol, an amido group containing fatty acid ester, ethoxylated and/or propoxylated pentaerythritol, an alpha-tocopherol ester, an ethoxylated and/or propoxylated fatty acid, and derivatives thereof; or mixtures of these additives.

  • Patent number: 6586509
    Abstract: A composition for an insulating layer of an electric cable wherein the composition contains an ethylene plastic as the base resin and further contains up to about 5% by weight of additives including antioxidant, and peroxide cross-linking agent. The composition is characterised in that the antioxidant additive includes a compound of the formula (V): R1(—(C+O)O—)k(CH2)1—S—(CH2)m(—OO(C═O)—)nR2 where R1 and R2, which are the same of different, are C7-C23 alkyl, C7-C23 alkenyl, R3—Ar—, Ar—R3—, or AR—, where R3 is C8-C24 alkyl and Ar is c6-c14 aryl; k and n, which are the same of different, are 0 or 1, l and m, which are the same or different, are integers ≧0; with the proviso that the compound is free from phenolic groups; and that the compositions is free from compounds having the formula (VI): R—O—(C═O)—CH2CH2SCH2CH2—(C═O)—O—R where R is a C8-C20 alkyl group.
