Abstract: Solid gas-permeable synthetic polymeric articles are chemically filled with a filler compound formed in situ. These deposits are produced by diffusing one or more diffusion compounds into a solid gas-permeable polymer and reacting or decomposing the diffusion compound(s) to form deposits throughout the article. The compounds may be preferentally deposited in a planar zone of sheet material in an amount sufficient to cause the sheet to split.

Abstract: Hexaorgano distannanes of the general formula R.sub.3 Sn-SnR.sub.3 significantly reduce or eliminate the discoloration which occurs when mixtures containing an alkali metal salt of a lactam are stored under an inert atmosphere for extended periods of time at temperatures between ambient and 100.degree.C. R in the foregoing formula represents a monovalent hydrocarbon radical containing between 1 and 20 carbon atoms.

Abstract: Cellular vinyl chloride polymers are prepared in the presence of a blowing agent and a diorganotin dimercaptide such as di-n-butyltin bis(dodecyl mercaptide). These organotin compounds are unique in that they activate the blowing agent to achieve maximum gas evolution at conventional processing temperatures while imparting a superior level of heat stability to the polymer. The dimercaptide is preferably employed in combination with a specified organotin derivative of a carboxylic acid, alcohol or phenol and/or metal salts of carboxylic acids containing between 4 and 18 carbon atoms wherein the metal is selected from Group IIB of the Periodic Table.

Abstract: Polymerization of epoxides and mixtures of epoxides with lactones and vinyl compounds, polymerizable through the action of cationic catalysts, is controlled by providing, in association with a radiation-sensitive catalyst precursor, a gelation inhibitor in the form of a cyclic amide in which the amide nitrogen atom contains unsubstituted hydrogen.

Abstract: A composite frame-like holder for a plurality of articles such as containers, a blank for the composite holder, and a method of forming the holder from the blank. The composite holder is an aggregate of singly or multiply severable holder units which can be severed from the composite in a manner that maintains the integrity of the severed unit and of the remaining composite. Each unit has a sloping leg panel with an aperture for receiving an article, a vertical side panel and a top panel foldable over the article and having means adjacent its edge for securing it to the holder unit. The method includes folding the blank along its center line to place its sections in superimposed, substantially mirror-image juxtaposition, securing one section to the other along their center strips, severing the center line, depositing containers in leg panel apertures and securing the containers to the thereby formed holders.
