Abstract

Improved drying oils are obtained by heating at 200 DEG to 300 DEG C for 1 to 3 hours, 100 parts of a drying oil derived from a conjugated diolefin having from 4 to 6 carbon atoms, preferably dissolved in an inert hydrocarbon boiling between 80 DEG and 250 DEG C., with 5 to 40 parts of a cyclodiolefin such as cyclopentadiene or methyl cyclopentadiene or their dimers. The wetting properties of the products may be improved by reaction with up to 2.5 per cent by weight of maleic anhydride before or after the reaction with the cyclodiolefin. Diolefins specified for preparing the drying oil are butadiene-1,3; isoprene; 2,3-dimethyl butadiene-1,3; piperylene and methyl pentadiene-1,3; and from 0 to 40 parts of styrene may also be included. The drying oils may be prepared by continuous or batch polymerization in an inert diluent such as naphtha, mineral spirits, butane, xylene, benzene, toluene, cyclohexane, or mixtures, or a modifying diluent, e.g. butene-2, which results in limited copolymerization and chain termination. Other diluents listed are vinyl ethyl, vinyl isobutyl, diethyl and diisopropyl ethers, dioxane, anisole and phenetole. Finely dispersed sodium is used as catalyst, preferably in conjunction with 1 to 50 per cent of a C1 to C5 aliphatic alcohol such as isopropanol or t-butanol. Alternative catalysts are potassium, sodium hydride, sodium alloys and Alfin-type catalysts. Acetic acid is used at the end of the reaction to destroy residual catalyst and the solution of the product is neutralized, filtered, preferably fractionally distilled and then concentrated to an intrinsic viscosity of 0.1 to 0.4. The viscosity may be further increased by heat bodying and naphthenate or octoate driers may be added. The improved drying oils may be used in varnishes and enamels to give films of increased chemical resistance and flexibility.
