Pulse radiolysis study of polymerization kinetics

  • E. Takács
Proceedings of the PULS'97


The kinetics of radiation initiated polymerization of HDDA and HDDMA were investigated in cyclohexane solutions by pulse radiolysis with transient spectroscopic detection. The maxima of the transient absorption spectra observed below 300 nm were shifted to longer wavelength with increasing the monomer concentration indicating a change in the structure of the intermediates. In HDDA solution of 10 mmol·dm−3 concentration a second peak appears at ∼330 nm as a consequence of the onset of oligomer radical formation. In HDDMA solution oligomer formation can be detected at higher concentration because of the lower reactivity of this monomer. The rate constants of termination (2k t ) were determined at different monomer concentrations.
