Abstract:
A process for making an unsaturated polyetherester resin useful for making curable thermoset resin compositions comprising reacting at least one acid-terminated unsaturated polyetherester resin with at least one aromatic polyol having at least one non-primary hydroxy group to produce an unsaturated polyetherester resin at least partially end-capped with an aromatic polyol;wherein the at least one aromatic polyol is represented by the formula ##STR7##wherein Ar.sub.1, Ar.sub.2 and Ar.sub.3 each independently represents an aromatic group; R.sub.1, R.sub.2, and R.sub.3 each independently represents a non-aromatic predominantly hydrocarbyl group; each X and X' independently represents a hydrocarbylene group, a hydrocarbylidene group a divalent hetero atom or group, an ester linkage, or a combination thereof; each X can also represent a covalent bond, h and k each independently represent an integer equal to 0 or 1; j represents an integer in the range from 0 to 5; and m, n, and p each independently represent an integer in the range from 1 to 5, provided that at least one hydroxy group of formula (I) is a nonprimary hydroxy group.
