Abstract: 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.

Abstract: A mechanical agitation-free method of making a homogeneous mixture of polyvinyl chloride solids and at least one liquid additive and/or particulate solid additive without mechanically-agitating or melting the polyvinyl chloride 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 polyvinyl chloride solids and the liquid additive and/or particulate solid additive for a period of time sufficient to substantially intermix the polyvinyl chloride solids and the liquid additive and/or particulate solid additive, while maintaining temperature of the heterogeneous mixture above the freezing point of the liquid additive, below the melting point of the particulate solid additive, and below the melting temperature of the polyvinyl chloride solids, thereby making the homogeneous mixture without mechanically-agitating or melting the polyvinyl chloride solids.
