Abstract

The kinetics of the first steps of electron beam (EB) initiated polymerization in cyclohexane solutions of hexanediol diacrylate (HDDA) and hexanediol dimethacrylate (HDDMA) were investigated by pulse radiolysis with transient spectroscopic detection. The maxima of the transient UV absorption spectra attributed to α-carboxyalkyl radical in HDDA solution were shifted to longer wavelength by increasing monomer concentration from 1 mmol dm-3 to 50 mmol dm-3, indicating the onset of oligomer radical formation. In HDDMA solutions the shape of the transient spectra did not change significantly as a result of the lower reactivity of this monomer. The rate parameters of termination (2kt) were determined for both monomers at different concentrations.
