ABSTRACT:
A method for producing a phenol foam plastic, consisting in that polycondensation of phenols with formaldehyde is conducted with simultaneous foaming and curing in the presence of a foaming agent and an acid or alkaline catalyst. Used as the phenols are pyrocatechol, hydroquinone, resorcinol, 5-methyl resorcinol, shale alkyl resorcinols, shale total phenols, or various combinations of said phenols. The method is simple and permits obtaining a foam plastic with improved physico-mechanical properties.
