Abstract: Coated internal surfaces of molding apparatus and a process for reducing the amount of sticking of material on the internal surface of a molding apparatus are disclosed. The coated substrate and the process both employ release compositions having very low surface tensions comprising (1) a linear or branched polymer containing ionic functional moieties and (2) a perfluorocarbon compound having a counterionic character. Such compositions dissolve in volatile acidic or basic solutions and result in salt precipitates which adhere to substrates upon the evaporation of the volatile acidic or basic solution.

Abstract: AR-Cyclic sulfonium, fused polynuclear areneoxides exemplified by the structural formula: ##STR1## polymerize readily upon exposure to ultraviolet light and/or heat to yield water-insoluble resins useful as adhesives, coatings, films and the like. Fused polynuclear zwitterions containing more than one areneoxide and cyclic sulfonium group per molecule crosslink under such conditions.

Abstract: Compounds of the formula ##STR1## wherein: EACH R individually is H, OH or C.sub.1 -C.sub.4 alkoxy;Each R' individually is H or C.sub.1 -C.sub.4 alkyl, and a is 1 or 2;Each sulfur is ortho or para to a phenolic oxygen;x is 0 or a positive number;y is 0 or a positive number;Z is a bridging group of the formula:(1) --O--, --S--, --O(C.sub.m H.sub.2m)O-- where m is 1-6, and .SIGMA.(x+y)=1;(2) --CR".sub.2 -- where R" is C.sub.1 -C.sub.4 alkyl, and .SIGMA.(x+y)=1; or(3) --CH.sub.2 -- and .SIGMA.(x+y)=1-20;Are produced in the process comprising the steps of:(a) reacting chlorine or sulfuryl chloride with a solution comprising a cyclic polymethylene sulfide (e.g. thiophane), iodine and HCl dissolved in liquid sulfur dioxide, thus forming a chlorine complex of the cyclic sulfide; and(b) reacting the chlorine complex from step (a) with the appropriate phenol in liquid sulfur dioxide.
