ABSTRACT:
A partially or fully cured thermosetting product which includes a cured and molded product of a thermosetting composition. The composition includes 70% to 99% by weight of at least one thermosetting resin or compound and 1% to 30% by weight of at least one toughening agent. The toughening agent is at least one hyperbranched dendritic macromolecule formed of ester units, optionally in combination with ether units.
