   その他of from 150° to 160° C., 490 parts

実験手順

At a temperature of from 150° to 160° C., 490 parts by weight of the glycide ester of branched monocarboxylic acids (2 moles) having an average carbon number of about 13* are added to 146 parts by weight of adipic acid (1 mole). Subsequently, at the same temperature, 296 parts by weight of phthalic anhydride (2 moles) are added to the formed dihydric ester alcohol. When the acid number of 120 is reached the ester chain length is extended by adding 490 parts by weight of the same glycide ester of branched monocarboxylic acids previously added above (2 moles) to the formed ester dicarboxylic acid to give the corresponding ester diol to which 296 parts by weight of phthalic acid (2 moles) are then added. As soon as the acid number is 65, the temperature is lowered to 130° C., and 88 parts by weight of ethylene oxide are added to the formed ester dicarboxylic acid to yield the corresponding ester diol.
