Abstract

The heats of polymerization for two unsaturated polyester resins are presented using two free radical initiator systems. The first was 1% methyl ethyl ketone peroxide/0.2% cobalt octoate (12%) and the second was 2% benzoyl peroxide/0.2% dimethylanyline. The heats of reaction were measured using a differential scanning calorimeter under dynamic and isothermal modes. Infrared spectroscopy and exotherm peak temperature test were employed to further establish the differences between the initiators and to determine the influence of three fillers (sand, clay, and flyโ€ash) on the cure reaction.

The influence of temperature and the initiator concentration on the curing of an unsaturated polyester resin was studied by means of differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR). It was established that there is an isoconversional relationship of the typ
