Immobilized epoxy advancement initiators |
| abstract |
ABSTRACT OF THE DISCLOSURE This invention is directed to a process for reacting at an elevated temperature (a) an epoxy resin or a thioepoxide bearing an average of more than one vicinal epoxide or thioepoxide group per molecule with (b) a polyhydric phenol, a polyhydric thiophenol, a carboxylic acid or a carboxylic acid anhydride. The invention is characterized by conducting the reaction in the presence of sufficient quantity of (c) a trihydrocarbyl phosphine or quaternary phosphonium cation which bear on the average per molecule more than one moiety corresponding to the formula wherein Z is -O- or -S-, R3 at each occurrence is independently a moiety essentially inert in this process, and w is an integer from 0 to 4, so as to promote the reaction of (a) with (b) and (c). These phosphorous compounds are not readily extractable from the resulting resins. |
