Abstract:
The disclosure relates to a tie resin formulation for use as a tie layer in a multilayer structure. The resin includes a first polyolefin grafted with an ethylenically unsaturated carboxylic acid, an ethylenically unsaturated acid derivative or a combination thereof, and having a density of 0.857 to 0.885 g/cm 3 , and 0.001 to 0.20 weight percent (wt.%) of a catalyst comprising at least one Lewis acid, where the resin includes the catalyst and up to 99.999 wt. % of the first polyolefin, where the wt. % is based on a total weight of the resin.
Abstract:
The present invention is a moisture crosslinkable polymeric composition comprising a siloxane-functional polyolefin polymer and a thermally-treated carbon black. The invention also includes a coating prepared from the moisture crosslinkable polymeric composition as well as a wire-and-cable construction made by applying the coating over a wire or a cable.

Abstract:
Silane-grafted polyolefin composition comprising a brominated, flame retardant additive is prepared by a process comprising the step of contacting within a reaction- extrusion zone operated at grafting conditions: A. A polyolefin, B. A hydrolysable unsaturated silane, C. A free radical generator, and D. Halogenated polyaryl alkane, e.g., decabromodiphenyl ethane, such that at least a portion of the hydrolysable unsaturated silane is grafted to the polyolefin. The silane-grafted polyolefin is crosslinked after extrusion from the zone, typically as a wire and cable coating, upon exposure to moisture.
Abstract:
The present invention is a moisture-crosslinkable polymeric composition comprising (a) a silane-functionalized olefinic polymer, (b) an acidic silanol condensation catalyst, and (c) a secondary-amine-containing antioxidant composition. The antioxidant composition can be (1) a secondary amine substituted with two aromatic groups or (2) a combination of a first antioxidant and a secondary amine antioxidant substituted with at least one aromatic group. The moisture-crosslinkable polymeric compositions can be used for making fibers, films, pipes, foams, and coatings. Notably, the compositions may be applied as a coating over a wire or a cable.
