Method for producing novolac resin and novolac resin |
| abstract |
The present invention provides a method for producing novolac resin in which phenols is reacted with aldehydes under mild conditions and efficiently producing novolac resin having low molecular weight, and in which phenols is reacted with aldehydes in the presence of catalyst containing boron compound represented by formula (I) B-(OR)3 (wherein R represents hydrogen or alkyl having 1 to 10 carbon atoms) and acid having pKa of 5.0 or less. |
