Dielectric relaxation in segmented copolyurethane imides

The dielectric relaxation and molecular mobility of multiblock segmented copolyurethane imides based on pyromellitic anhydride and aromatic diamines and 2.4-methylene diisocianate (forms a rigid urethane imide segment) terminated polybutylene adipate (Mn 2700) (forms a soft segment) were studied by...
