Notes:
The reactivity of both the peroxide (2-tert-butylperoxy-2-methyl-5-hexene-3-yne) and hydroperoxide (2-hydroperoxy-2-methyl-5-hexene-3-yne) monomers in the radical copolymerization was compared. Using the Alfrey-Price Q and e scheme, Hammett correlations, and MNDO quantum-chemical model it was shown that both peroxy- and hydroperoxyisopropylic substituents pronounce a similar positive effect of hyperconjugation. Despite that these monomers showed different reactivity due to the ability of the hydroperoxide monomer to form complexes with protonoacceptors. IR spectroscopy was employed for the evaluation of energies of hydrogen bonds and equilibrium constants. © 1996 John Wiley & Sons, Inc.
