반응 단계
Into a reaction vessel equipped as in Example A was charged 1064 grams tetramethoxymethyl glycoluril (TMMGU) and 532 grams hydrogenated bisphenol-A which was melted and heated to 120° C. 14 grams of Polycat 200 catayst was added slowly over a 30-minute period at 110°-120° C. to control foaming. The batch temperature was then raised slowly to 160° C. and foaming controlled with 2 grams additions of Quadrol. Total Quadrol added is 10.4 grams. Upon reaching a tack temperature of 80°-85° C., the batch was discharged into a tray. The product, a methoxy-methyl-functional copolymer of TMMGU and HBPA, has a tack temperature of 84° C., a viscosity at 50% non-volatile content in meta-pyrol of K and a methoxy equivalent weight of 212. A small amount of self-condensation had also occurred in this reaction in addition to the primary methoxyhydroxyl reaction.
