Abstract
The invention relates to polycycloacetals of formula I ##STR1## wherein n is an integer from 1 to 500, x and y are each independently of the other 0 or 1, R.sup.1 is a carbon atom or a tetravalent hydrocarbon radical having a molecular weight not greater than 1000 and which can additionally contain ether oxygen atoms or oxygen atoms in hydroxyl, carbonyl or epoxy groups, and R.sup.2 is a tetravalent hydrocarbon radical derived from a dialdehyde or a diketone. The polycycloacetals can be used together with conventional hardeners and/or curing catalysts for epoxy resins for the fabrication of cross-linked (cured) products having good properties, especially having excellent fastness to solvents, light and weathering.
