Monoacrylates of trihydric phenols and method for producing same

, (2008/06/13)

Compounds of the general formula I STR1 in which R is a hydrogen or halogen atom, a cyanide or an alkyl group having 1-4 carbon atoms and R1 is a hydrogen or halogen atom, nitro, alkyl, alkoxy, aryl, aryloxy, acyl or alkoxycarbonyl group, are prepared by esterifying two adjacent OH groups to give the cyclic carbonate, esterifying the free OH group with (meth)acrylic acid and selectively hydrolyzing the carbonate. The compounds are free of polyunsaturated impurities and can be used for preparing purely linear polymers.
