A Comparison of the Thermal Crosslinking Behavior of Polyquinoxalines with and without Reactive Side Groups,

Abstract

The crosslinking behavior of various polyquinoxalines without the use of a trifunctional crosslinking agent is investigated with the purpose of comparing the thermal crosslinking reactivity of linear polymers with and without active side chains. Torsional braid analysis is used to follow the changes in glass transition temperature which is used as the kinetic parameter. It is found that in general, linear polymers that have reactive side groups such as methyl or carboxyphenyl groups along the polymer chain, crosslink more rapidly than the analogues without these groups.
