    Abstract: Compounds R1OCOO(CH2)4OCOOR2, wherein R1 and R2 are saturated chlorine-containing aliphatic radicles with 6 to 18 carbon atoms in all, are plasticizers for synthetic resins. Resins mentioned are vinyl polymerizates, e.g. polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl esters of organic acids, polyacrylic compounds or interpolymerizates of such vinyl compounds, aldehyde and ketone resins, cellulose esters, e.g. nitrocellulose and cellulose esters of organic acids, and phenol- or maleic acid-modified colophony esters. Conventional plasticizers, fillers, stabilizers and dyestuffs may be present. The incorporation of the ester with the resin may be effected in the usual way, e.g. by kneading or rolling or the ester may be added to an aqueous emulsion of the resin. Generally 10-60 per cent of ester is present. The compositions may be used in lacquers and worked in the usual way to yield lamin , films, foils or bands, for sticking surfaces together, for coating wood, metal, fabrics or paper and for the preparation of cable compositions, oilcloths, artificial leather and floor coverings. In examples: (1) P.V.C. is plasticized with the bis-omega-chlorbutyl carbonate of butanediol-1,4 and in the remainder lacquers are made comprising together with conventional volatile solvents and the bis-omega-dichlorbutylcarbonate of butanediol-1.4 (2) pyroxylin; (3) a synthetic resin derived from cyclohexanone and methylcyclohexanone by caustic soda treatment, carbon black and pyroxylin; (4) crude castor oil and pyroxylin; (5) a U.-F. condensation product and pyroxylin; and (6) polystyrenes.ALSO:Compounds R1OCOO-(CH2)4OCOOR2 wherein R1 and R2 are saturated chlorine containing aliphatic radicles with 6 to 18 carbon atoms in all are obtainable by reaction of the bischlorcarbonic acid ester of butanediol-1,4 with monohydric saturated chlor-alcohols such as omega-chlorbutanol and its homologues or ethylene glycol mono-omega-chlorethyl ether, or by reacting chlor-carbonic acid esters of these chlor-alcohols with butanediol-1,4. They are plasticizers (c.f. Group IV (a). In an example (1) the bis-omega-chlor-butyl-carbonate of butanediol-1,4 is made by reacting butanediol-1,4 with chlor-butyl-chlor-carbonate.ALSO:Natural resins e.g. colophony and dammar, are plasticized with a compound R1OOCO(CH2)4 OCOOR2, where R1 and R2 are saturated chlorine-containing aliphatic radicles with 6 to 18 carbon atoms in all.
