Abstract

Polymerizable ethylenically unsaturated compounds are photopolymerized by irradiation with radiation of wavelength between 2500 and 7000 in the presence as a catalyst of an alpha-hydrocarbon substituted acyloin of the formula <FORM:0741570/IV(a)/1> where Ar represents a monocyclic aromatic radical having its free valency bond attached to nuclear carbon, and R represents a monovalent hydrocarbon radical containing 1 to 9 carbon atoms, such as alpha-methyl benzoin, alpha-ethyl benzoin, alpha-propyl benzoin, alpha-tertiary butyl benzoin, alpha-(n-nonyl) benzoin, alpha-allyl benzoin, alpha-phenyl benzoin, and alpha-benzyl benzoin. Ethylenically unsaturated compounds specified are isoprene, chloroprene, linear polybutadienes, vinyl acetate, vinyl propionate, diallyl phthalate, methyl vinyl ketone, vinyl ethers, styrene, divinyl benzene, methyl acrylate, ethyl acrylate, methyl methacrylate, isobutyl methacrylate, methyl alpha-chloracrylate, ethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate, glycerol trimethacrylate, methacrylic anhydride, acrylonitrile, methacrylonitrile, methacrylamide, alkyd resins derived from glycerol, phthalic acid, and methacrylic acid, diethyl fumarate, unsaturated polyesters derived from maleic and fumaric acids and ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, pentamethylene glycol, and pentaerythritol which may also contain coconut oil, vinyl and vinylidene chlorides, and divinyl formal, and mixtures thereof. Also present in the reaction mixture may be allyl glycidyl ether as an inhibitor of colour formation. The process may be carried out by bulk, solution, emulsion, or granular polymerization procedures. Specifications 708,643 and 741,294, [Group XX], are referred to.ALSO:Alpha-benzyl benzoin is prepared by adding sodium methoxide (10.8 parts) to benzoin (20 parts) dissolved in dry benzene (176 parts) in a nitrogen atmosphere. After stirring and refluxing for 5 hours the reaction mixture is cooled to room temperature and benzyl bromide (51.3 parts) is added. Stirring is continued for 1 hour at room temperature and then for 5 hours at 50-55 DEG C., the reaction mixture is filtered and the filtrate distilled under reduced pressure leaving a residue of alpha-benzyl benzoin which is recrystallized from heptane and then from alcohol. Specification 708,643 and 741,294, [Group XX], are referred to.
