This invention concerns a stabilized packaging environment for a particulate vinyl lactam polymer, particularly polyvinylpyrrolidone particles, which comprises a sealed, oxygen-impervious receptacle containing the polymer particles and a separate air permeable package within the receptacle containing a water moistened oxygen scavenging agent, preferably iron powder, an iron (II) salt, ascorbic acid or a mixture of such agents.

Novel and known functionally substituted phenoxyalkyl-, thiophenoxyalkyl- and pyridyloxyalkylsilanes are prepared by reacting substantially equimolar amounts of an alkali- or alkaline earth metal phenoxide, thiophenoxide or pyridyloxide with a haloalkylsilane under anhydrous conditions using a dipolar, aprotic solvent in combination with a liquid hydrocarbon.

Heat-resistant, polyorganosiloxane elastomers are prepared by reacting a linear, difunctional polyorganosiloxane with a silicon-containing crosslinking agent and a stannous salt of a monoethylenically unsaturated monohydroxy monocarboxylic acid as the curing catalyst. A filler can optionally be included in the formulation. The present catalysts are unique in that they impart a relatively long working life to the uncured composition yet do not catalyze the depolymerization reaction at elevated temperatures as do conventional organotin catalysts such as dibutyltin dilaurate.
