Abstract
PURPOSE: To prepare the title resin having good workability and giving a laminate free from thin spot, by synthesizing the resol-type phenolic resin in the presence of 3-methylpentane-1,3,5-triol.
CONSTITUTION: The objective water-soluble resol-type phenolic resin having an average molecular weight of about 220W230 is prepared either by the polycondensation of phenol with formaldehyde in the presence of an alkaline catalyst adding about 5.3W16 g (per 1 mole of phenol) of 3-methylpentane-1,3,5-triol, or by adding the same amount of the triol to the phenolic resin prepared without adding the triol. A resol-type phenolic resin for the improvement of impact strength can be obtained by adding a trace of aniline to the reaction mixture to obtain a resin having an average molecular weight of about 320W330, and then adding 3-methylpentane- 1,3,5-triol to the resin.
