The polycondensation reaction between maleic anhydride and 1,6-hexanediol, withp -toluenesulfonic acid as catalyst has been carried out. The product has been analyzed spectroscopically and the molecular weight determined by endgroup analysis and gel permeation chromatography. The influence of spatia

Syntheses of unsaturated polyesters were investigated by the divalent metal salts of mono(hydroxyethyl) phthalate-ethylene glycol-anhydrides-epoxide reactions. As anhydrides, phthalic anhydride and maleic anhydride were used, and propylene oxide and 1,a-butylene oxide were the epoxides used. The met

The influence of the double bond on the thermodynamic parameters, T m, AH,. and AS,. of some unsaturated aliphatic polyesters has been found to depend on the number of --CH2--groups separating the double bond from the ester linkage. Thus, T,,'s of the polyesters derived from trans-4octene-l,8-dioic
