POLYALKYLENE POLYOL ESTERS OF DIALKYLAMINOBENZOIC ACID AND THEIR USE IN PHOTOINITIATED CURING PROCESSES

摘要

Amine compounds of general formula (I), wherein: each R<1> independently represents an alkyl group; each R<2> independently represents an alkyl group; each group X independently represents a polyalkylene polyol moiety wherein hydroxyl groups of the polyol moiety are optionally alkylated; n and m independently represent 1, 2 or 3; and each Q is independently selected from hydrogen or halogen atoms, and alkyl, acyl, nitro, cyano, alkoxy, hydroxy, amino, alkylamino, sulphinyl, alkylsulphinyl, sulphonyl, alkylsulphonyl, sulphonate, amido, alkylamido, alkoxycarbonyl, halocarbonyl and haloalkyl groups, processes for their preparation and intermediate compounds are described. Compounds of general formula (I) are useful as radiation curing agents in polymerisation processes.
