A molded article exhibiting sustained release gas action to combat insects, without incurring odor build-up, comprising the product of curing a composition comprising 0,0-dimethyl-0-(2,2-dichlorovinyl)phosphate, an ethylenically unsaturated polyester, a vinyl monomer copolymerizable with the polyester, at least one solid or liquid filler, and an ethylenically unsaturated compound of the formula HZ ANGLE C=C ANGLE (I) O=CY X in which X is -OR or -OH, Y is -H and Z is -COOR, or X is -OH, Y is -COOR and Z is -H, or X is -O- or >N-R, Y is >CO and Z is -H, in which case X and Y are bonded together to form an anhydride or imide ring, and R is an aliphatic radical with up to 12 carbon atoms. Desirably curing is effected in the presence of a peroxide of the formula A-C-O-O-C-B (II) PARALLEL PARALLEL OO in which A and B each is alkyl, aryl, aralkyl, alkoxy or aryloxy of 6 to 12 carbon atoms. |
