## Abstract A study has been carried out on the kinetics of the emulsion polymerization of 2,3βdimethylbutadieneβ1,3. The kinetic treatment of Smith and Ewart was applied for the direct determination of the absolute propagation rate constant __k~p~__. The following expression was obtained: __k~p~__
The vibrational structure of the 3pr Rpdbcrg transition of 2.3-dimethplbutadienc has been recorded and analyzed. A signifknt reduction in frequency of the lower -CHs torsion on excitation is observed in bo?h this state and in the 4fI and 4f2 Rfdbee states.
