    Abstract: Propenyl ether monomers of formula VA(OCH.dbd.CHCH.sub.3).sub.nwherein n is an integer from one to six and A is selected from cyclic ethers, polyether and alkanes are disclosed. The monomers are readily polymerized in the presence of cationic photoinitiators, when exposed to actinic radiation, to form poly(propenyl ethers) that are useful for coatings, sealants, varnishes and adhesives. Compositions for preparing polymeric coatings comprising the compounds of formula V together with particular cationic photoinitiators are also disclosed, as are processes for making the monomers from allyl halides and readily available alcohols. The process involves rearranging the resulting allyl ethers to propenyl ethers.

    Abstract: A method is provided for making silicone-organic block polymers, such as polydimethylsiloxane-polystyrene block polymers resulting from the thermal generation of free-radicals in the presence of free-radical polymerizable organic monomer. A silicone prepolymer is used having chemically combined pinacolate groups in the backbone or terminal positions which are capable of generating free-radicals upon thermolysis and which retain chemically combined remnants of such pinacolate diradicals which serve as connecting sites for free-radical polymerized organic blocks.
