Popis: The polyester and diimide–diacid-modified polyester prepolymer have been synthesized with different molecular weights through melt polycondensation of 1, 6-hexanediol (HD), trimethylol propane (TMP), isophthalic acid (IPA), diimide diacid, and phthalic anhydride (PA) at various molar ratios. The prepolymers were then mixed with an equivalent phenol-blocked TDI and /or HMDI in m-cresol in deriving the polyester urethane varnishes. The degree of crosslinkage and thermal behavior have been investigated here. © 1993 John Wiley & Sons, Inc.
