Abstract
Novel polymers of a glycidyl ester of an aliphatic carboxylic acid, the acid containing from 16 to 30, preferably from 16 to 24, carbon atoms, are prepared by polymerization in the presence of a Friedel-Crafts catalyst or an organo-metallic compound. The carboxylic acid is preferably a saturated aliphatic monocarboxylic acid such as stearic acid, behenic acid or a mixture thereof. Preferred catalysts are boron trifluoride, tin tetrachloride, antimony pentachloride or mixtures thereof, which are advantageously in the form of an ether- or water-complex and diluted by a diluent such as dioxan. Polymerization may take place at a temperature between the melting-point of the monomer and 200 DEG C., especially between 50 DEG C and 100 DEG C. The resulting polymers are obtained as waxes, having degrees of polymerization from 2 to 12, preferably from 4 to 10. The waxes have good solubility in balsam turpentine, gasoline and trichloroethylene and may be employed as polishing agents.ALSO:Novel polymers of a glycidyl ester of an aliphatic carboxylic acid, the acid containing from 16 to 30, preferably from 16 to 24, carbon atoms, are prepared by polymerization in the presence of a Friedel-Crafts catalyst or an organo-metallic compound.
