Abstract
Glycolysis of polyethylene terephthalate was carried out with crude glycerol. Three fractions were separated from the product obtained on the basis of their solubility in water. Three kinds of unsaturated polyesters were synthesized by polycondensation of each fraction with propylene glycol and maleic anhydride.
To prepare unsaturated polyester resins, usually styrene is added to unsaturated polyesters. In the present work, unsaturated polyester resins of low styrene emission were obtained by substituting part of styrene with methyl methacrylate. The solidification was carried out using cobalt naphthenate and methylethyl ketone peroxide as accelerator and initiator, respectively. Some basic physicomechanical properties of the solidified systems were studied.
