摘要： Compositions useful as coatings for wire and cable comprise, in weight percent (wt %) based on the weight of the composition: (A) 10 to 62 wt % of a silane-grafted ethylene polymer (Si-g-PE) having a silane content of 0.5 to 5 wt % based on the weight of the Si-g-PE, wherein the Si-g-PE is made from an ethylene polymer (base resin) having the following properties. (1) Density of 0.875 to 0.910 g/cc; (2) Melt index (MI, 12) of 8 to 50 g/10 min (190° C./2.16 kg); and (B) 38 to 90 wt % of a halogen-free flame retardant (HFFR); (C) 0 to 0.3 wt % of an antioxidant; and (D) 0 to 1 wt % of a silanol condensation catalyst.

摘要： Flooding compounds for telecommunications cables. Such flooding compounds contain a polymeric filler and a branched olefinic fluid. The branched olefinic fluid has an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. Additionally, the average number of carbons per molecule in the branched olefinic fluid is from 25 to 200.

摘要： A polyethylene copolymer blend consisting essentially of (A) an ethylene/unsaturated carboxylic ester bipolymer and (B) an ethylene/unsaturated carboxylic ester/carbon monoxide terpolymer. The polyethylene copolymer blend is defined by constituents (A) and (B) and at least one omitted material that would have otherwise restricted a physical property of the blend. The (A) ethylene/unsaturated carboxylic ester bipolymer is defined by features comprising choice of unsaturated carboxylic ester, unsaturated carboxylic ester comonomeric content in weight percent (wt %), and bipolymer melt index (I2; 190° C., 2.16 kg) in grams per 10 minutes (g/10 min.). The (B) ethylene/unsaturated carboxylic ester/carbon monoxide terpolymer is defined by features comprising choice of unsaturated carboxylic ester, unsaturated carboxylic ester comonomeric content in wt %, carbon monoxide comonomeric content in wt %, and terpolymer melt index (I2; 190° C., 2.16 kg) in g/10 min. Also formulations, cured polymer products, strippable semiconductive insulation shield layers, coated conductors, methods of making and using same.
