High-temperature chemical transformations of tetracarboxylic acid dianhydrides with aromatic diamines in rolivsan matrix

Thermochemical transformations of ternary thermosetting systems consisting of rolivsans, aromatic tetracarboxylic acid dianhydrides, and aromatic diamines were studied by dynamic mechanical and thermal analysis. The influence of the composition and curing conditions of these systems on the thermomechanical properties of new glassy network block copolymers exhibiting enhanced heat resistance was determined.
