Claim 1
Independent Claim
132 words
A process for combatting gastro-intestinal worms in poultry or warm-blooded domestic animals which comprises orally administering to said poultry or warm-blooded domestic animals an anthelmintic effective amount of a composition comprising a complex chemical compound of the calcium salt of O-methyl-O-(2,2-dichlorovinyl)phosphoric acid with O,O-dimethyl-O-(2,2-dichlorovinyl)phosphate and a thermoplastic resin comprising a co-polymer obtained by copolymerizing 30 to 60 wt. parts of a conjugated diene compound selected from the group consisting of butadiene, isoprene and chloroprene with 70 to 40 wt. parts of a monovinyl monomer compound copolymerizable with said diene compound and selected from the group consisting of ethylene, propylene, styrene, vinyl chloride, vinyl acetate, acrylonitrile, methyl acrylate, vinyl butyl ether, vinylidene chloride, methacrylaonitrile, alpha-methylstyrene, and methacrylate, in the presence of from 0.5 to 5.0 wt. parts of divinylbenzene as a cross-linking agent.
