| abstract | 303,905. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Jan. 12, 1928. [Convention date]. Void [Published under Sect. 91 of the Acts]. Phenol-aldehyde condensation products. - A synthetic resin is prepared by mixing an excess of formaldehyde with a. monohydric and a polyhydric phenol, the final stage of the reaction being effected with pressure and heat. A body which yields formaldehyde may be used instead of formaldehyde, and in a modification the semicondensation products of formaldehyde with a monohydric and with a polyhydric phenol may be mixed and then heated under pressure. Fillers may be added. In an example, phanol, resorcinol and paraformaldehyde are mixed together, the first stage of the condensation being effected at ordinary temperature, a catalyst being unnecessary. |
