Abstract
Resinous compositions are made by forming water-soluble resins by partially dehydrating the mixtures resulting from (a) the reaction of phenol and formaldehyde using a caustic alkali catalyst, and (b) the reaction of acetone (1 mol.) and formaldehyde (1 to 6 mols.) using an organic amine catalyst, and mixing the resins to form a composition containing 25 to 75 per cent by weight of either resin. In the example, phenol and formalin are condensed in the presence of caustic soda and under reduced pressure, the reaction mixture being neutralized with phosphoric acid after cooling and dehydrated by distillation, while a mixture of acetone, formalin and the low molecular weight reaction product of a previous batch is condensed in the presence of aqueous dimethylamine, the reaction mixture being partially dehydrated by distillation. In the bonding of glass wool, equal parts of the constituent resins are added to a mineral oil in water emulsion and sprayed on to a mat of glass wool, the mat being subsequently baked at 200 DEG C. Hardening of the mixtures may be accelerated by conventional heat-hardening agents.
