| titleOfInvention | Process for producing modified phenolic resin |
| abstract | A process for producing a modified phenolic resin which comprises heating and stirring a heavy oil or pitch together with a formaldehyde compound and a phenol represented by the formula (I) (wherein R1 is a C2-10, linear or branched, unsaturated hydrocarbon group having one or two unsaturated bonds; p is 1 or 2; X is C1-5 alkyl; and q is 0 or 1) in the presence of an acid catalyst to conduct polycondensation, the amounts of the formaldehyde compound and the phenol being <u>0.3</u> to 25 mol in terms of formaldehyde amount and <u>0.5</u> to 50 mol, respectively, per mol of the heavy oil or pitch. The modified phenol obtained by the process has flowability around room temperature because it has a far lower melting point than conventional modified phenolic resins obtained from a heavy oil or pitch. It further has a low melt viscosity and hence excellent moldability. When used in combination with an epoxy resin, the modified phenol can give a molded article excellent not only in heat resistance, moisture resistance, corrosion resistance, adhesion, etc. but also in dimensional stability and mechanical properties including strength. |
