Kinetics of the geminal recombination of aromatic radicals in liquid polymers

Conclusions Laser photolysis was used to determine the kinetics of the geminal and bulk recombination of radical pairs formed in the transfer of a hydrogen atom from p-cresol to triplet benzophenone in liquid polymers. In a very viscous polymer matrix containing a nonviscous plasticizer, the bulk recombination of the low-molecular-weight radicals proceeds at a very high rate as in nonviscous liquids.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 437–438, February, 1987.
