摘要： PROBLEM TO BE SOLVED: To obtain the subject resin, producible without any reduction in resin yield, capable of manifesting a low viscosity and a low pour point and useful as a raw material for reaction and a plasticizer, etc., by the presence of a specific alcohol in a specific proportion at the time of condensation reaction of an aromatic hydrocarbon with formaldehyde. SOLUTION: This low-viscosity aromatic hydrocarbon formaldehyde resin is obtained by carrying out the condensation reaction of (A) an aromatic hydrocarbon with (B) formaldehyde and (C) a 1-8C aliphatic alcohol in the presence of (D) an acidic catalyst and prepared so as to provide 5-18wt.% oxygen atom concentration in the resin and 20-15,000cP viscosity at 25 deg.C. The resin is obtained by charging, e.g. the components A, B and C at a ratio so as to afford 1:(0.5-5) molar ratio of the components A:B and 1:(0.2-1) molar ratio of the components B:C and conducting the condensation reaction in the presence of the component D at 80-100 deg.C temperature.

摘要： PURPOSE:An epoxy resin composition especially suitable for the production of a copper-clad laminate, consisting of a resin having a phenolic hydroxyl group in a molecule and an epoxy resin derived from xylylenediamine or bis-aminomethyl- cyclohexane. CONSTITUTION:A resin composition consisting of (A) a resin having a phenolic hydroxyl group in a molecule and (B) an epoxy resin obtained by the reaction of xylylenediamime or bis-amino methyl-cyclohexane with an epihalohydrin or beta- methylepihalohydrin. The resin A is blended with the rsin B in amounts to give 0.15-7.0moles of epoxy groups in the resin B per eqnivalent weight of hydroxyl group in the resin A. A condensation product of alpha.alpha-dimethoxy-p-xylene and a phenol, an aromatic hydrocarbon formaldehyde resin modified by phenol, etc. may be cited as the resin A.

摘要： PROBLEM TO BE SOLVED: To provide a low viscosity phenol-modified aromatic hydrocarbon- formaldehyde resin having less free phenol which is improved in problems regarding the conventional production of the low viscosity phenol-modified aromatic hydrocarbon-formaldehyde resin. SOLUTION: The aromatic hydrocarbon formaldehyde resin is modified by a small amount of phenols using a weak acid such as an amine salt of p- toluenesulfonic acid, oxalic acid, maleic acid or the like as a weak acid catalyst.

摘要： PROBLEM TO BE SOLVED: To obtain a novolak-type phenol-modified copoly (aromatic hydrocarbon/formaldehyde) resin having a short setting time and a high thermal hardness. SOLUTION: This resin is obtained by reacting (A) a copoly (aromatic hydrocarbon/formaldehyde) resin having 2.0-3.0 substituents per one aromatic ring on an average with (B) a phenol in the presence of an acidic catalyst. This resin is also obtained by reacting (A) a copoly(aromatic hydrocarbon/ formaldehyde) resin having 2.0-3.0 substituents per one aromatic ring on an average with (B) a phenol and (C) formaldehyde in the presence of an acidic catalyst. Xylene or mesitylene is preferable as an aromatic hydrocarbon raw material for producing a copoly(aromatic hydrocarbon/formaldehyde) resin.
