    Abstract: A process for preparing α, ω-functional siloxane compounds in a purity of greater than or equal to 90% includes contacting a monohydrosiloxane compound of formula 1 with oxygen in the presence of a platinum group catalyst, without adding water, to form the α, ω-functional siloxane compound in a purity of greater than or equal to 90%; wherein n is 0, 1, or 2; R1 is fluoroethyl, methyl or phenyl; and R2 is substituted alkyl, epoxyalkyl, oxetanylalkyl, substituted oxaalkyl, epoxyoxaalkyl, oxetanyloxaalkyl, alkenyl, alkylalkoxysilyl, substituted alkylaryl, and substituted arylalkyl.

    Abstract: Diaryliodonium salts are disclosed, as well as a method for preparing them, in which one of the aryl groups bonded to the positively-charged iodine ion contains a methyl substituent, and the other one contains a hydroxyl-substituted alkoxy group. The salts are synthesized from (o, m, or p)-iodotoluene, as opposed to iodobenzene, and therefore do not pose a carcinogenic risk. In addition, the present salts are unexpectedly more soluble in most organic solvents, as well as in nonpolar monomers, than the corresponding benzene catalysts. The salts are useful as cationic photoinitiators, cationic thermal initiators (often combined with a cocatalyst, e.g. copper), and as starting materials in the synthesis of urethane-containing iodonium salts.

    Abstract: Unsaturated or polyunsaturated, conjugated or nonconjugated hydrocarbons are reacted with an oxidizing agent including hydroperoxides and monopersulfate compounds in the presence of phase-transfer catalysts. Suitable hydrocarbons include ricinic compounds such as castor oil and dehydrated castor oil. The phase-transfer catalysts include novel tungsten peroxo complexes, such as quaternary ammonium tetrakis (diperoxotungsto) phosphates, and crown ethers. Other additives utilized include pH buffers and alkaline compounds including alkali metal and alkaline earth metal carbonates, and solvents.

    Abstract: A method of accelerating the cure rate of an epoxy curing composition includes combining a cycloaliphatic epoxyalcohol monomer, a non-hydroxyl-containing epoxy monomer and a cationic photoinitiator to form an epoxy curing composition, and exposing the curing composition to a source of radiation. The resulting polymers and copolymers are branched polyethers containing hydroxyl functionality.
