Synthesis and crosslinking of polyethers with nadimide derivative pendant groups

Polyethers with nadimide derivatives pendent groups have been prepared by ring‐opening polymerization of nadimide glycidyl derivatives. The structure of the linear polymers has been confirmed by spectroscopic methods. Properties such glass transition temperatures and thermal resistance have been measured and related to their chemical structure. Crosslinking studies have been carried out by DSC and TGA. Kinetic parameters could be obtained by dynamic method. The crosslinking causes an increase in Tg of the system and it has been possible to relate this increase to the chemical structure of the network.
