摘要： Moisture-crosslinkable compositions having an alkoxysilane functionalized ethylenic polymer, a polymeric brominated flame retardant, antimony trioxide, and a silanol condensation catalyst. The polymeric brominated flame retardant and the antimony trioxide are present in quantities sufficient to provide a molar ratio of antimony to bromine (Sb/Br) in the range of from 0.79 to 1.70. Additionally, the polymeric brominated flame retardant and the antimony trioxide are present in the composition in a combined amount of greater than 35 wt %. Such moisture-crosslinkable compositions are suitable for use in preparing crosslinked articles of manufacture, such as for wire-and-cable applications.

摘要： Articles made from a moisture-curable, polymeric composition comprising in weight percent based on the weight of the composition: (A) 2 to less than 80 weight percent (wt %) of an ethylenic polymer with (1) a crystallinity at room temperature of 34% to 55%, or 65% to 80%, and (2) a melt index (I2) of 0.1 to 50 decigrams per minute (dg/min); (B) 3 to 30 wt % of a halogenated flame retardant; (C) 3 to 30 wt % an inorganic antimony flame retardant; and (D) 0 to 10 wt % of at least one of an inorganic flame retardant other than the inorganic antimony flame retardant, e.g., zinc oxide exhibit enhanced ACBD properties in comparison to articles alike in all respects except made from a composition comprising an ethylenic polymer without the requisite crystallinity at room temperature.

摘要： A method of making a homogeneous mixture of polyolefin solids and liquid additive without melting the polyolefin solids during the making The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the liquid additive for a period of time sufficient to substantially intermix the polyolefin solids and the liquid additive together and while maintaining temperature of the heterogeneous mixture above the freezing point of the at least one liquid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

摘要： A method of making a homogeneous mixture of polyolefin solids and a particulate solid additive without melting the polyolefin solids or the particulate solid additive during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the particulate solid additive for a period of time sufficient to substantially intermix the polyolefin solids and the particulate solid additive together and while maintaining temperature of the heterogeneous mixture below the melting point of the at least one particulate solid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids or the at least one particulate solid additive.
