Abstract
909,842. Alkylene oxide modified novolaks, and esters prepared therefrom. DISTILLERS CO. Ltd. Oct. 21, 1959 [Oct. 22, 1958], No. 33787/58. Class 2(5) Polyols are prepared by reacting, at an elevated temperature, a phenol-formaldehyde novolak resin, derived from phenol itself and which has at least three phenolic units per molecule, with ethylene oxide and/or 1:2-propylene oxide under atmospheric pressure and under anhydrous conditions, part of said novolak resin being in the form of its alkali metal salt. The examples describe the preparation of the novolaks and their subsequent convertion in part to their alkali metal salts. The polyol prepared in Example 1 is soluble in ethanol and acetone. The polyols may be esterified with fatty acids derived from drying and semi-drying oils to give esters which are compatible with white spirit and xylene; cobalt, calcium and lead naphthenate driers may be added to the ester solutions. Fatty acids utilized in the examples are those derived from linseed oil and dehydrated castor oil. Specifications 757,392, 760,698, 760,699, 775,459 and 775,460 are referred to.
