LOW SOFTENING POINT PHENOL NOVOLAC RESIN, METHOD FOR PRODUCING SAME, AND EPOXY RESIN CURED PRODUCT USING SAME |
摘要 |
<p>Disclosed is a low softening point phenol novolac resin characterized by having a constitutional unit represented by the general formulae (1) below and a melt viscosity at 150°C of 20-100 mPa·s. Also disclosed is a method for producing such a low softening point phenol novolac resin. In the formulae (1), R represents at least one divalent arylene group selected from a biphenylene group and a xylylene group represented by the following general formulae (2): and may further contain a constitutional unit represented by the following general formula (3): (wherein R<SUP>4</SUP> represents a hydroxyl group or an alkyl group having 1-6 carbon atoms); m and n represent numbers satisfying m/n = 0.04-20; R<SUP>1</SUP>, R<SUP>2</SUP> and R<SUP>3</SUP> may be the same as or different from one another and respectively represent a hydroxyl group or an alkyl group having 1-6 carbon atoms; and p, q and r respectively represent an integer of 0-2.</p> |
