Abstract

Modified phenol-aldehyde resins suitable for use in moulding compositions and for impregnating fibrous sheets which are then laminated, are obtained by reacting a phenol and formaldehyde with oxidized rubber prepared as described in Specifications 417,912, 462,613 and 462,627, [all in Group V], in the presence of an acid catalyst, e.g. oxalic, formic or maleic acid. Specification 538,922 also is referred to.
