Abstract
Foams comprising blends of thermoplastic and thermoset materials wherein the thermoset forms a discontinuous phase in a continuous thermoplastic phase are described. Foams comprising an uncured thermoset and unreacted radiation-activatable curing agent in a thermoplastic matrix are also described. Additionally described are batch and continuous methods for making the foams. Particular uses for the foams, such as flexographic mounting tapes, are also described.
