Ghenadii Korotcenkov,Igor Proninmeters of a matrix. The latter may differ significantly under stress. Current data concerning the kinetics of oxidation of stressed polymers are reviewed in terms of the relation between stressed polymer structure and molecular motion on the one hand and chain radical reaction kinetics on the other.

Polymer Stability in Aggressive Media,ining heteroatoms in the side groups. The following problems are discussed: catalysis in aggressive liquid media, such as solutions of acids, bases and salts; the reactivity and mechanisms of transformation of chemically unstable bonds in various polymers; specific features of the chemical degradati

Characterisation of Oxidised Polyolefines by Reaction with Sulphur Dioxide,therefore of vital importance. Traditional methods based on carbonyl index or oxygen absorption have many disadvantages and sensitive techniques have been developed based on reactions with sulphur dioxide; these give insights regarding the sites of oxidative attack. The formation of sulphur-containi
