| Résumé : |
The kinetics of obtaining polyesters and dioctylphthalates were compared. The polyester was obtained by a two-step reaction from adipic acid and polyethylene glycol, and the esterification of the free carboxy groups by 2-ethylhexanol in the presence of catalysts. The dioctylphthalate was obtained by the same catalysts: metal salts, titanium alcoholates and their mixtures. The influence of the molecular weight of the raw materials on the kinetics of preparing the resulting products was determined. The effects of dioctylphthalate and polyester on the properties of the mixtures and coatings from bisphenol A-based epoxy resins were determined. |
