[Class 95] The gelling tendency of liquid adhesives comprising solutions of plastic polymerized chlproprene in a solvent is diminished by adding thereto diethylamine and an ethanolamine. The chloroprene may be the product described in Specification 468,435, [Group IV], and the solvent may be benzene, trichlorethylene, toluene, - xylene or carbon tetrachloride. The composition may also contain zinc oxide, magnesium oxide, sulphur, and an accelerator such as a butyraldehyde-aniline condensation product.
