Abstract
The dynamic mechanical properties of polyurethane (PU) grafted epoxy p olymer networks have been investigated. The glass transition region is successfully broadened on variation of the degree of phase separation . The tensile strength initially increases with increasing PU content and reaches its maximum value when the PU/epoxy ratio is about 20/80.
