Abstract
An olefin polymer composition is disclosed which contains (by weight): (a) from 0.3 to 3% of a complex of general formula: R.(MeX.sub.3).sub.y wherein R is an amine; Me is bismuth or antimony; X is chlorine or bromine; y is a number from 0.3 to 4.0; (b) from 0.1 to 1% of poly(1,4-diisopropylbenzene); (c) from 0.1 to 0.5% of an organic epoxide; the balance to 100% being an olefin polymer.
Claims4
An olefin polymer composition comprising:
- (a) from 0.3 to 3% of a complex of formula:
- R.(MeX.sub.3).sub.y
- wherein R is an amine selected from the group consisting of dicyandiamide, guanamine, 2-guanidinoimidazole, melamine, isophoronediamine, and piperazine, which are optionally substituted with an alkyl, aryl or acyl group, and compounds containing from 2 to 9 triazine rings either condensed or bonded to one another with at least one --NH group;
- Me is bismuth or antimony;
- X is chlorine or bromine;
- y is a number from 0.3 to 4.0;
- (b) from 0.1 to 1% of poly(1,4-diisopropylbenzene) of formula:
- H--[C(CH.sub.3).sub.2 --(C.sub.6 H.sub.4)--C(CH.sub.3).sub.2 ].sub.n --H
- where n is a number from 3 to 7;
- (c) from 0.1 to 0.5% of an organic epoxide;
- the balance to 100% being an olefin polymer, wherein all percentages are based on the total weight of the composition.
