    Abstract: Styrene is polymerixzed with optionally up to 45% by w. of acrylonitrile a - or nuclear-methyl styrene, and mono- or di-chlorostyrene, at 80-180 DEG C., the polymerization being carried on until the coversion if 45-95% and the remaining monomers and any diluent being removed by degassing in vacuo, and prior to degassing there is added to the polymerization mixture, before or during polymerization, 0.1-5% of an ester of a dimer or trimer of a fatty acid which is oleic, linoleic, linolenic or elaidic acid, with a C1- 18 alcohol and/or an ester of a C18 acid with an alconol which has been obtained by hydrogenation of the above dimer or trimer and/or an alcohol which h as been obtained by hydrogenation of the above dimer or trimer. the polymerization may be carried out in the presence of up to 50% of diluent e.g. ethylbenzene. The ester may be te butyl or ethylhexyl ester of the fatty acid. The polymerization may be continuous. The styrene may be polymerized in the presence of a rubber comprising 25% styrene and 75% butadiene.

    Abstract: The invention comprises compounds of the general formula:- in which R and R1 are C1-C4 alkyl groups, X is an oxygen or sulphur atom and Y is C1-C4 alkoxy, allyloxy, phenoxy, nitrophenoxy, mono-or dialkylamino with 1 to 4 carbon atoms in the alkyl groups, cycloalkylamino, anilino, pyrrolidino, piperidino, C1-C4 alkylmercapto, C1-C4 alkyl sulphonyl, phenylmercapto or phenyl sulphonyl group. They may be obtained by reacting a compound of the formula (RO) (R1O) P(X) Hal in which Hal is a halogen atom, e.g. chlorine, bromine, or iodine, and R, R1 and X are as defined above with a 1-substituted butene-(3)-ol-(2) of the formula HO.CH.(CH2Y).CH =CH2 in which Y is as defined above. The reation may be carried out in the presence of an inert organic diluent, e.g. an aromatic, aliphatic or cycloaliphatic hydrocarbon or an aliphatic chlorohydrocarbon and it is advantageous to effect the reaction in the presence of an agent which binds hydrogen halide, e.g. pyridine, aniline, methylaniline, triethylamine, tripropylamine or other amine whose boiling point is above the reaction temperature or an alkali metal carbonate or bicarbonate. The reaction is preferably effected at about 10 to 130 DEG C. e.g. at 15 to 75 DEG C. Examples are given for the production of compounds in which R and R1 are each ethyl, X is S and Y is -NHC3H7, N(C2H5)2, SC2H5, p.NH.C6H5. p.SO2C6H5, SO2C2H5, phenoxy, cyclooctylamino, pyrrolidine, p.S.C6H5, ethoxy, allyloxy, and p.nitrophenoxy respectively. Examples are also given for the production of (CH3O)2P(S)O.CH(CH2SC2H5) CH=CH2 and the corresponding O,O- diisopropyl and O,O-dibutyl compounds, (CH3O)2 P(O)O CH(CH2.O. C6H5)CH=CH2, (iso C3H7O)2 P(S)OCH (CH2S.C6H5) CH=CH2, and (C2H5O)2 P(O)O CH(CH2SC2H5)CH=CH2. The products have insecticidal properties.
