In recent years there have been comparatively few developments in phenolic resin technology apart from the so-called Friedel-Crafts polymers introduced in the 1960s and the polybenzoxazines announced in 1998 which are discussed briefly at the end of the chapter. [Pg.635]

The efficiency of ethylene glycol-water as a delignifying solvent has been demonstrated by Gast and Puls (10). Results showed that sufficiently delignified pulps could be obtained. Also, the lignins produced showed promising results as extenders in phenolic resin adhesives. [Pg.236]

OSL Impurities. It was also of interest to determine the impurities removed from crude OSL by reslurry in aqueous sodium bicarbonate, which was done to improve its usefulness in phenolic resins (Cook, P. M., Eastman Kodak at Kingsport, TN, personal communications, 1987). Extraction and acetylation procedures, involving methylene chloride, acetic anhydride pyridine... [Pg.328]
