1341875 Anthelmintic compositions KUREHA KAGAKU KOGYO KK 19 April 1971 [10 March 1970] 23708/71 Heading C3P [Also in Division A5] An anthelmintic composition comprises (a) a complex of calcium O-methyl-O-(2,2-dichlorovinyl) phosphate and O,O-dimethyl- O-(2,2-dichlorovinyl) phosphate and (b) a copolymer of 30-60 parts of a conjugated diene, 70-40 parts of a vinyl or vinylidene monomer and 0À5-5 parts of a polyolefinically unsaturated cross-linking agent. The conjugated diene may be butadiene, chloroprene or isoprene. The vinyl or vynlidene monomer may be ethylene, propylene, styrene, α-methyl styrene, vinyl chloride, vinylidene chloride, vinyl acetate, vinyl butyl ether, acrylonitrile, methacrylonitrile, methyl acrylate or methyl methacrylate. The cross-linking agent may be divinyl benzene. The composition may also include another thermoplastic resin (e.g. polymethyl methacrylate, polyvinyl chloride, polyvinyl acetate, polystyrene or an ethylenevinyl acetate copolymer), a plasticizer (e.g. dioctyl phthalate) and a filler (e.g. silica powder). The composition is extruded into granules. |
