They are distinguished by satisfactory solubility in the acid-curable resin systems, can be stored virtually indefinitely in the dark and, when exposed to shortwave light, make it possible to cure the resins by acid catalysts at a relatively low temperature.

    摘要： 2-Oxo-2-alkoxy-5-dialkylphosphono-1,2-oxaphospholanes of the formula ##STR1## in which R.sub.1 to R.sub.7 are hydrocarbon radicals can be prepared from .alpha.,.beta.-unsaturated ketones and 2 or more moles of a dialkyl phosphite. Obviously .alpha.-ketophosphonates are intermediates of this reaction, as these compounds react with 1 or more moles of dialkyl phosphite in yielding the oxaphospholanes too. Both reactions are promoted by alkaline catalysts.The new oxaphospholane derivatives are considerably stable against thermal decomposition. They are compatible with polymeric materials and can be used as flame protecting agent for plastics and resins, for example, in polyurethane foams.

    摘要： Cationically polymerizable compounds, for example epoxide compounds, can be polymerized photochemically using a catalyst combination consisting of an aromatic iodonium salt and a ketone of the formula I, II or III ##STR1## in which n is 1 or 2 and Ar, X, X', R.sup.1, R.sup.2 and R.sup.3 are as defined in claim 1. In this combination, the ketones act as a co-catalyst and drastically accelerate the photopolymerization, although they are not able to initiate a cationic photopolymerization on their own.
