Abstract
Official abstract text for this publication.
A melt blended composition comprising, in weight percent (wt %) based upon the weight of the composition: (A) 55 to 94.99 wt % of a thermoplastic polymer, (B) 5 to 44.99 wt % of a moisture curable polymer, and (C) 0.01 to 5 wt % of a moisture condensation catalyst exhibits enhanced rheological and mechanical properties as compared to a composition alike in all aspects save for the presence of a moisture curable polymer.
First claim
Opening claim text (preview).
What is claimed is: 1. A melt blended composition comprising, in weight percent (wt %) based upon the weight of the composition: a non-foam composition comprising (A) 55 to 94.99 wt % of a thermoplastic polymer that is one or more non-functionalized polyethylenes, each polyethylene comprising at least 50 mol % units derived from ethylene, (B) 5 to 44.99 wt % of a silane functionalized polyethylene, (C) 0.01 to 5 wt % of a moisture condensation catalyst, (D) optional carbon black, (E) optional additive selected from the group consisting of antioxidant, light stabilizer, UV stabilizer, cling additive, processing aid, and combinations thereof, and components (A), (B), (C), (D), and (E) amount to 100 wt % of the composition. 2. The composition of claim 1 in which the condensation catalyst is a Lewis acid or a Lewis base. 3. The composition of claim 1 in which the condensation catalyst is dibutyl tin dilaurate. 4. The composition of claim 1 in which the condensation catalyst is sulfonic acid. 5. A crosslinked composition of claim 1 . 6. A wire or cable sheath comprising the composition of claim 1 . 7. A wire or cable comprising the sheath of claim 6 . 8. The composition of claim 1 wherein the thermoplastic polymer comprises two polyethylenes, each polyethylene different than the other. 9. The composition of claim 8 wherein the carbon black (D) is present. 10. The composition of claim 9 wherein the thermoplastic polymer comprises three polyethylenes, each polyethylene different than the other. 11. The composition of claim 10 wherein the additive (E) is present and the additive includes an antioxidant, a light stabilizer, and a processing aid.
