Novolak aralkyl resin, preparation process thereof and composition containing said resin |
| abstract |
Preparation process for a novolak aralkyl resin having excellent heat resistance and curing property by reacting 0.4 to 0.8 mol of an aralkyl compound based on one mol of the low molecular weight novolak containing 90% by weight or more of bi-nuclear novolak in the presence of an acidic catalyst, the process comprising at first melting the low molecular weight novolak, heating it up to a reaction temperature, then adding 0.001 to 0.05% by weight of the acidic catalyst to the total amount of the low molecular weight novolak and the aralkyl compound, then continuously adding the aralkyl compound for reaction, neutralizing the residual acidic catalyst after the completion of the reaction, a novolak aralkyl resin obtained by the preparation process and a novolak aralkyl resin composition containing said resin. |
