Abstract

The kinetics of esterification of bisphenol‐A based epoxy resin with acrylic acid in presence of triphenylphosphine has been studied. The reaction exhibits a first‐order rate dependence with respect to [Epoxy] and [Catalyst]. A first‐order dependence of rate with respect to [Acid] has been observed during a particular kinetic run. However, a retarding effect of [Acid] on the rate has been observed by increasing the initial concentration of acid. A suitable mechanism consistent with the kinetic data is proposed and discussed.

## Abstract In this study, cardanol‐based epoxidized novolac resins and methacrylic acid were used to produce cardanol‐based epoxidised novolac vinyl ester resins. The reactions were conducted under nonstoichiometric condition using triphenylphosphine as catalyst in the temperature range of 80–100Β°

The effects of the concentration of triphenylphosphine as a catalyst on the cure reaction of the biphenyl epoxy/phenol novolac resin system were studied. The kinetic study was carried out by means of the analysis of isothermal experiments using a differential scanning calorimeter. All kinetic parame
