According to the present theories of plastic toughening
it is impossible to enhance the toughness
stiffness and/orheat resistance of plastics simultaneously by using rubber. A series of novel nano-rubber particles (UFPR) were introduced
which were prepared through irradiating common rubber lattices and spray drying them. Epoxies toughened with UFPRshowed a much better toughening effect than those with CTBN
and the heat resistance of epoxy was unexpectedly elevated.For polypropylene toughening
UFPR can improve the toughness
stiffness and heat resistance of PP simultaneously.These special toughening effects overcome the deficiencies in rubber toughening technology and are worth further investigating.
