In this work, the curing kinetic of an unsaturated polyester resin, mixed with styrene as curing agent, was studied by means of diffential scanning calorimetry (DSC) and infrared (IR) spectroscopy. Investigations were made in situ during curing and post-curing periods. The enthalpy ( DH cop ) charac

Fractions of an unsaturated polyester resin (UP), based on 1 mol maleic anhydride, 1 mol isophthalic acid, 1 mol propylene glycol, and 1 mol diethylene glycol, were obtained from an industrial reactor at various times during polyesterification. They were characterized by 1 H-NMR and chemical titrati
The change of the viscoelastic behavior of an unsaturated polyester resin during curing was followed by a vibrometric technique, while the portion converted to gel in applied films was also determined by means of extraction with a solvent. Some relationship between the viscoelastic properties and th
Curing kinetics of unsaturated polyester resin system exhibiting apparent induction periods was investigated by modeling free radical initiation and propagation processes. The isothermal curing induction time as well as the maximum-rate time provided the same activation energy in the Arrhenius relat
The curing of unsaturated polyesters in the presence of organic and inorganic Γllers was studied by rheology and di β erential scanning calorimetry (DSC). A commercial resin was used as unsaturated polyester and pressed olive stones, which are an agricultural by-product, talc and quartz in di β erent
The curing reaction of a divinyl ester resin with different proportions of styrene-4, 20, and 40% by weight-was investigated by differential scanning calorimetry (DSC) using isothermal and dynamic modes. The different constraints on the reaction rate was globally considered, taken the reaction as di
