Decay of Radicals in Polymer Matrices

  • A. Plonka
Part of the Lecture Notes in Chemistry book series (LNC, volume 40)

Abstract

It was rationalized (Emanuel 1981) that to describe the kinetic processes involving radicals in polymer matrices one has to use an integro-differential equation which for the case of simple monomolecular reactions reads
$$- d\left[ R \right]/dt = \int_0^\infty {kR\left( k \right)dk}$$
(4.1)
where R(k) denotes the distribution of radicals according to their reactivity expressed in terms of reaction rate constant k.
