Abstract
New polyhydroxy-containing compounds represented by the formula ##SPC1## Wherein A is --O-- or an alkylidene group having 1 to 4 carbon atoms, Y.sub.1, Y.sub.2, Y.sub.3 and Y.sub.4 are independently selected from --OH or ##SPC2## (wherein R is selected from hydrogen, a halogen atom and an alkyl group having 1 to 4 carbon atoms), X and X.sub.1 are independently selected from hydrogen, a halogen atom or the group ##SPC3## (wherein R is as defined above), R.sub.1 and R.sub.2 are selected from hydrogen, a hydroxyl group, and an alkyl group having from 1-4 carbon atoms, m is the number 0 or 1 and n and n.sub.1 are numbers independently selected from 1 to 20. A process for their preparation is disclosed as well as new epoxy resins prepared therefrom which may be represented by the formula ##SPC4## Wherein A, m, n, and n.sub.1 are defined above and Y.sub.1, Y.sub.2, Y.sub.3 and Y.sub.4 are independently selected from --OH and the group ##EQU1## (wherein R is selected from hydrogen, a halogen atom or an alkyl group having from 1 to 4 carbon atoms), R.sub.1 and R.sub.2 are selected from hydrogen, and alkyl group having from 1 to 4 carbon atoms and the group ##EQU2## X and X.sub.1 are independently selected from hydrogen, a chlorine group and the group ##EQU3## (wherein R is as defined above), m is a number selected from 0 and 1 and n and n.sub.1 are numbers independently selected from 1 to 20 wherein at least 2 of the groups selected from Y.sub.1, Y.sub.2, Y.sub.3, Y.sub.4, X and X.sub.1 are the group ##EQU4##
