ABSTRACT:
Phosphine oxide-containing polyarylene ethers and sulfides can be reacted with organoamines to form novel graft copolymers (with monofunctional amines) or novel crosslinked thermosetting network compositions (with multifunctional amines). The network materials show desirable resistance to a variety of organic solvents including chloroform.
