    • 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 ##EQU1## in which X is --OR or --OH, Y is --H and Z is --COOR, orX is --OH, Y is --COOR and Z is --H, orX 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, andR is an aliphatic radical with up to 12 carbon atoms. Desirably curing is effected in the presence of a peroxide of the formula ##EQU2## in which A and B each is alkyl, aryl, aralkyl, alkoxy or aryloxy of 6 to 12 carbon atoms.
