Abstract: A crosslinkable composition of a polymeric thermoplastic and/or elastomeric material which is susceptible to scorching when processed at elevated temperatures, prior to crosslinking, in the presence of a free radical initiator, is protected against such scorching by the incorporation therein of a mixture of at least one hydroquinone compound and a sulfur accelerator. This mixture may also contain at least one monomeric allylic, methacrylic, acrylic or diene type coagent. The mixture exhibits a synergistic effect resulting in improved scorch protection for peroxide cured systems when compared with the protection afforded by the components singly.

Abstract: A process is disclosed for the efficient production of high purity alkane sulfonic acid and/or alkane sulfonyl chloride product wherein a compound of the formula RSX, where X is hydrogen or --SR.sup.1 and R and R.sup.1 are alkyl radicals is continuously reacted with chlorine in aqueous hydrochloric acid to produce a turbulent evolution of hydrochloride gas, passing the reactants through stationary mixing elements to promote plug-flow, and separately withdrawing a product. Apparatus for this process is also disclosed.

Abstract: A process for the preparation of 142 is provided, wherein 1130 is fluorinated in the gas phase in the presence of a catalyst which is a supported or unsupported fluorinated salt of one or more of chromium, iron, niobium, nickel, antimony, tin, tantalum or titanium. 142 is a known foam blowing agent.

Abstract: Orthophosphite ions produced by oxidation of hypophosphite in an electroless nickel plating bath can be removed by precipitation with an alkali metal or alkaline earth metal cation such as calcium. In order to avoid the precipitation of calcium sulfate and the generation of large amounts of particulates in the bath, nickel sulfate can be replaced by a nickel salt of an alkylsulfonic acid or hypophosphorous acid, whose anion forms a soluble salt with an alkali metal or alkaline earth metal cation.

Abstract: Novel peroxyoxalate compositions of Structure A, ##STR1## and use of the novel monoperoxyoxalates of Structure A as initiators for polymerizing ethylenically unsaturated monomers and for curing of unsaturated polyester resins are disclosed.

Abstract: Dual cure organotin salts of strong organic acids, the use of such salts as catalysts and an improved process for producing the catalysts are provided. The catalysts are capable of effectively catalyzing esterification and transesterification reactions and urethane, silicone, melamine, ester and acrylic forming reactions and can simultaneously catalyze more than one reaction in a mixture of urethane, silicone, amino, ester and acrylic polymer forming reactants to produce a polymer mixture.

Abstract: Partially epoxidized compounds obtained from Diels Alder adducts of dicyclopentadiene with fatty oils having a iodine number of 70 or greater and their transesterification products with C.sub.1 to C.sub.10 alkanols are disclosed. 100% solids radiation and heat curable coating compositions containing the epoxidized compounds and/or their transesterification products are also disclosed.

Abstract: This invention relates to aqueous solutions containing Ni cation and hypophosphite anion which have a Ni cation concentration greater than 36 grams/liter. Such solutions have utility in electroless nickel plating baths and processes as make-up solutions and replenishing solutions. The increased concentration of Ni cation results from the addition of the nickel salt of an alkyl sulfonic acid to the solution.
