Abstract
High efficiency stable aqueous resoles which contain low concentration of free phenol and free formaldehyde and cause substantially less pollution of the atmosphere than prior art resins. The resoles are prepared by a two-stage reaction which controls the molecular weight, water tolerance and the ratio of methylolated 2,2'-, 2,4'- and 4,4'-dihydroxydiphenylmethanes. Stability is promoted by inhibition of the crystallization of bis(4-hydroxy-3,5-dimethylolphenyl)methane.
