Title: Treatment of chlorinated rubber and products thereof
IPC: C08L15/02
Filed: 1937-05-22
Abstract: A chlorinated rubber product for use in the preparation of lacquers is obtained by heating chlorinated rubber with drying or non-drying oils, plasticizers, or oil-modified alkyd resins or mixtures thereof to a temperature above 100 DEG  C., preferably to 130 DEG  C., for a period of 50-180 minutes; the ratio of chlorinated rubber to treating agent should be high, e.g. one part of chlorinated rubber may be used with one or two parts of treating agent.  Treating agents specified are linseed oil, linseed oil-stand oil, wood oil, wood oil-stand oil and castor oil; tricresyl phosphate, dimethylphthlate, butylstearate, triacetin and tributyl phosphate; and glycerine-phthalic acid ester resin previously boiled with drying or non-drying oils.  For use as a lacquer the reaction products may be dissolved in the usual solvents for chlorinated rubber, e.g. benzene hydrocarbons; in turpentine oil substitutes containing about 10 per cent of these solvents; in linseed oil varnish, train oil varnish, or resin varnish; or it may be combined with nitrocellulose as described in Specification 495,967.ALSO:A chlorinated rubber product for use in the preparation of lacquers is obtained by heating chlorinated rubber with drying or non-drying oils, plasticizers, or oil modified alkyd resins or mixtures thereof to a temperature above 100 DEG  C., preferably to 130 DEG  C., for a period of 50-180 minutes; one part of chlorinated rubber may be used with one or two parts of treating agent.
