Abstract
With the use of the assumption that the structure of an amorphous polymer can be presented as a set of frozen locally ordered regions surrounded by a loosely packed matrix, it is shown that a structure comprising a percolation cluster is formed in epoxypolymers, and in this case the glass-transition temperature is associated with the critical percolation probability, and the glass transition itself is considered as a phase transition.
