This work was undertaken to assay the possibilities of making useful copolymers from linseed and similar oils. Methyl esters of linoleic, conjugated linoleic, linolenic, and alkali‐cyclized linolenic acid have been copolymerized with ethyl acrylate at 60C and monomer reactivity ratios have been determined. In comparison with benzene or methyl stearate as inert diluents, all of these esters and several glycerides with conjugated or unconjugated unsaturation, and also 3,5,7‐decatriene as a model compound, retard the polymerization of ethyl acrylate. Methyl eleostearate and the decatriene are unusually strong retarders of polymerizations of styrene, acrylonitrile, and ethyl acrylate, increasing retardation in the order given. Several experiments on copolymerizations of acrylonitrile with linseed oil at 60‐130C show that the copolymerizations which incorporate much oil in the copolymer are slow but that the isolated copolymers have good drying and film‐forming properties.
