Abstract

A synthetic resinous composition hardenable at room or moderately raised temperature comprises a mixture of phenol-formaldehyde resol, an acid accelerator and 0.1-15 per cent of polyvinyl acetate, of partly hydrolysed polyvinyl acetate, of polyvinyl alcohol, or mixtures of two or more of these materials. The resol is formed from a phenol or a cresol and may be solid, liquid or a solution or dispersion of solid resin. Suitable accelerators are hydrochloric, sulphuric or a sulphonic acid. The accelerator is preferably added just before hardening, but the polyvinyl compound may be added to the phenol before reaction with the formaldehyde or during or after the reaction with the formaldehyde. The polyvinyl compound may be mixed with the acid accelerator. They may be dissolved or dispersed in solvents before incorporation. The products may be cast, used as adhesives, for the formation of expanded resins by inclusion of a gas generator or they may be dissolved to form lacquers or varnishes. Suitable solvents are methyl ethyl or butyl alcohol, methyl ethyl ketone or ethyl acetate. In examples: (1) phenol and /or aldehyde were refluxed with sodium hydroxide and the product dehydrated. The liquid resin is mixed with an alcoholic solution of polyvinyl butyral and sulphuric acid added to harden the mixture. The product may be used for sticking synthetic resin mouldings or for securing bristles in their holders; (2) polyvinyl alcohol is used instead of the butyral and hydrochloric instead of sulphuric acid; (3) polyvinyl acetate is mixed with p-toluene sulphonic acid and the mixture added to a liquid resin as in example (1). The product in solution in methylated spirit may be applied to acid-resisting paper, and abrasive grit is sprinkled on and the composition air-dried. A sizing coat of the resinous composition may then be applied. Reference has been directed by the Comptroller to Specification 553,437.
