EPOXY-AMINE MULTIMETHACRYLIC PREPOLYMERS, KINETIC AND STRUCTURAL STUDIES

Epoxy-amine methacrylated prepolymers are prepared in a 1-step synthes is by the reaction of Bisphenol A diglycidyl ether, glycidyl methacryl ate, and different diamines. The adaptation of these reactions to prod uction processes with a reduced reaction time requires a kinetic contr ol and the use of efficient catalysts. The comparative kinetic treatme nt of the epoxy-amine reaction in the frame of Horie's and Rozenberg's kinetic schemes have been made. Cases where an efficient acid catalys t is used are also examined. Structural studies of these reactions est ablished the occurrence of a Michael amine/double bond addition, when some amines are used. (C) 1995 John Wiley & Sons, Inc.
