Abstract
A suitably functionalized cycloaliphatic nitrile oxide can be used to convert unsaturated sites to alcohol or epoxy sites. The cycloaliphatic nitrile oxide may be useful in applications such as the preparation of polycarbonates, polyurethanes, or crosslinked polybutadiene, or poly(styrene-butadiene). The cycloaliphatic nitrile oxide is represented by the formula: ##STR1## wherein R' and each R are independently hydrogen, C.sub.1 -C.sub.12 alkyl, or halo; X and X' are independently hydrogen, halo, hydroxyl, or together with the carbon atoms to which they are attached form an epoxy group, with the proviso that at least one of X and X' is not hydrogen; and n is 1 or 2.
