Abstract

1,256,838. Phenolic resins. MITSUI TOATSU CHEMICALS Inc. 31 July, 1970 [1 Aug., 1969; 25 Aug., 1969], No. 37166/70. Heading C3R. [Also in Division D2] A phenol-formaldehyde resin of formula where n=0-10 and each A radical is an alkyl, cycloalkyl, aryl, aralkyl or halogen radical, is obtained by (a) reacting 0À6 to 1À0 mol. of formaldehyde or a formaldehyde-generator with 1 mol. of the corresponding phenol in the presence of an acidic catalyst and a solvent which forms an azeotrope with water, (b) dissolving the resultant polymer in aqueous alkali, (c) separating-off any remaining organic solvent and (d) acidifying the solution to precipitate the polymer. The water of reaction may be removed by azeotropic distillation. Phenols specified include cresol, ethyl phenol, propyl phenol, butyl phenol, amyl phenol, hexylphenol, iso-octyl phenol, decyl phenol, dodecylphenol, tetradecyl phenol, octadecyl phenol, pentadecyl phenol, cyclohexylphenol, phenylphenol, benzylphenol, alpha-naphthylphenol, beta - naphthylphenol, cetylphenol, chlorophenol, bromophenol, fluorophenol, nonylphenol and tert-butylphenol. A mixture of two phenols may be used (Example 4). Formaldehyde sources specified include paraformaldehyde and formalin. Acidic catalysts specified include p-toluene sulphonic acid, naphthalene - alpha - sulphonic acid, sulphuric acid and benzene sulphonic acid. Solvents specified include toluene, benzene, xylenes, trimethyl benzene, ethylbenzene, diethylbenzene, triethylbenzene, n-hexane, n-heptane, noctane, n-nonane, cyclohexane, methylcyclohexane, chloroform, carbon tetrachloride, trichloroethylene, tetrachloroethylene and chlorobenzene. Alkalis specified include NaOH and KOH. Neutralizing acids specified include hydrochloric, sulphuric, phosphoric, oxalic, formic and acetic. In Example 1, a papertreating composition comprises a polymer of the invention mixed with water, an anionic surface active agent comprising a sodium salt of a polymeric polycarboxylic acid and a butadiene-styrene copolymer.
