Novolak Aralkyl resin, preparation process thereof, and composition containing said resin |
| abstract |
A preparation process for a novalak aralkyl resin havingnexcellent heat resistance and curing properties involvesnreacting 0.4 to 0.8 mol of an aralkyl compound based on onenmol of the low molecular weight novolak containing 90% bynweight or more of bi-nuclear novolak in the presence of annacidic catalyst. The process comprises first melting thenlow molecular weight novolak, heating it up to a reactionntemperature, then adding 0.001 to 0.05% by weight of thenacidic catalyst to the total amount of the low molecularnweight novolak and the aralkyl compound, then continuouslynadding the aralkyl compound for reaction, and neutralizingnthe residual acidic catalyst after the completion of thenreaction. A novolak aralkyl resin obtainable by the abovenpreparation process, and a novolak aralkyl resinncomposition containing that resin, are also provided. |
