Abstract
Abstract Shaped articles having long term vapor emission comprising a thermosetting resin produced from an unsaturated polyester and a vinyl monomer copolymerizable therewith, containing an effective amount of 0,0-dimethyl-0-(2,2-dichlorovinyl)-phosphoric acid ester as pesticidally, e.g. insecticidally and/or acaricidally, active compound, in a ratio by weight of active compound to resin of e.g. about 0.25-2 : 1, and also containing a solid filler, and optionally a liquid filler.
