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.

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.

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.
