✦ Synopsis

Abstraet--Copolyesters have been synthesized by interfacial polycondensation of 2,2-bis(4-hydroxyphenyl)-propane or phenolphthalein as aromatic diol and ethylene glycol or polyethylene glycol as aliphatic diol in various mole ratios with terephtbaloyl or isophthaloyl chloride. Chemical compositions, dilute solution viscosities and solubility behaviours of these polymers have been investigated. The introduction of aliphatic diol in aromatic polyesters influences T 0, softening point, chemical resistance and thermal stability.

Network copolyesters were prepared from glycerol (Yg) and sebacic acid (10) with 10 -90 mol % of either succinic acid (4), 1,12-dodecanedicarboxylic acid ( 14), 1,18-octadecanedicarboxylic acid (20), or terephthalic acid (T). Prepolymers prepared by melt-polycondensation were cast from dimethylforma
