Synthesis and characterization of saturated and unsaturated copolyesters based on bis‐1,4‐(dicarboxymethoxy) benzene

摘要

AbstractSaturated copolyester were prepared by copolyesterification of bis‐1,4‐(dicarboxymethoxy) benzene and phthalic anhydride with diethylene glycol, triethylene glycol, tetraethylene glycol, 1,4‐butane diol, 1,2‐propane diol, and 1,6‐hexamethylene glycol. Also, unsaturated copolyesters were prepared by copolyesterification of bis‐1,4‐(dicarboxymethoxy) benzene and maleic anhydride with the same glycols. All the copolyester resins obtained have been characterized and unsaturated copolyesters in the form of films were determined. IR and1H‐NMR spectroscopy were used for both qualitative and quantitative analysis of the copolyesters resins and their hydrolyzate products, after curing with styrene. © 1992 John
