Abstract
Abstract This invention relates to polymerizable acrylic esters of the halogenated acetylenic alcohols, WHEREIN R represents hydrogen and a monovalent hydrocarbon containing one to ten carbon atoms, X is a halogen selected from the class consisting of chlorine and bromine, y represents a numerical value of 1 or 2, and n represents a numerical value of 1 to 3. These acrylic monomers are useful for the preparation of self-extinguishing homopolymers and copolymers; the diesters are also particularly useful as crosslinking agents for other monomers and polymers.
