Claims
- 1. A composition consisting essentially of a polyolefin and 1.0 to 5.0 weight percent, based on the total weight of the polyolefin, of an additive selected from
- (i) cyclic siloxanes containing at least one aromatic group attached to silicon through a silicon-carbon bond;
- (ii) liner siloxanes having the general formula HO{C.sub.6 H.sub.5 (CH.sub.3)SiO}.sub.x H wherein x has a value of from 2 to 10,
- (iii) linear siloxanes having the general formula RO{C.sub.6 H.sub.5 (CH.sub.3)SiO}.sub.x R wherein x has a value of from 2 to 36 and R is selected from a group consisting of CH.sub.3 O-- and ##STR3##
- 2. A composition as claimed in claim 1 wherein the additive is the cyclic siloxane (C.sub.6 H.sub.5 (CH.sub.3)SiO).sub.3.
- 3. A composition as claimed in claim 1 wherein the additive is the cyclic siloxane (C.sub.6 H.sub.5 (CH.sub.3)SiO).sub.4.
- 4. A composition as claimed in claim 1 wherein the additive is the cyclic siloxane (C.sub.6 H.sub.5 (CH.sub.3)SiO).sub.5.
- 5. A composition as claimed in claim 1 wherein the additive is the cyclic siloxane (C.sub.6 H.sub.5 (CH.sub.3)SiO).sub.6.
- 6. A composition as claimed in claim 1 wherein the additive is a linear siloxane having the general formula CH.sub.3 O(C.sub.6 H.sub.5 (CH.sub.3)SiO).sub.x CH.sub.3.
- 7. A composition as claimed in claim 1 wherein the additive is a linear siloxane having the general formula ##STR4##
- 8. An article which is an electrical cable in which the primary insulation layer is manufactured from the composition of claim 1.
- 9. An article which is an electrical cable in which the primary insulation layer is manufactured from the composition of claim 6.
- 10. An article which is an electrical cable in which the primary insulation layer is manufactured from the composition of claim 7.
