ABSTRACT:
A method of producing essentially haze-free isophthalic acid and polymethylolalkanoic acid-containing resins comprising reacting isophthalic acid, a polymethylolalkanoic acid, and a polyol in the presence of a catalytically effective amount of a catalyst selected from the group consisting of stannous oxalate, dibutyltin oxide, and tetrabutyl titanate at a temperature of between about 150.degree. C. and 230.degree. C. to produce haze-free resin.
