Abstract
The present invention provides a process for eliminating contaminants from epihalohydrin-derived epoxy resins. Another embodiment of the present invention is an epoxy product formed using said process. Yet another embodiment of the present invention is an epoxy derived in part from epihalohydrin wherein said epoxy is has a hydrolyzable halogen content of less than 10 ppm and an epoxide equivalent weight within 2 percent of the theoretical epoxide equivalent weight.
