Abstract
Abstract Novel products corresponding to the formula ##STR1## are produced by reacting an allyl halide (e.g., allyl chloride) or a vinylbenzyl halide (e.g., vinylbenzyl chloride) with an oxazoline or an oxazine. The novel compounds are polymerizable monomers and can be used to complex phenols.
