Abstract
Poly(arylene ether)s containing pendent ethynyl and substituted ethynyl groups and poly(arylene ether) copolymers containing pendent ethynyl and substituted ethynyl groups are readily prepared from bisphenols containing ethynyl and substituted ethynyl groups. The resulting polymers are cured up to 350.degree. C. to provide crosslinked poly(arylene ether)s with good solvent resistance, high strength and modulus.
Claims2
A poly(arylene ether) containing pendent ethynyl or substituted ethynyl groups prepared by reacting a bisphenol containing an ethynyl or substituted ethynyl group and having the structure ##STR5## wherein R is selected from the group consisting of hydrogen, n-C.sub.4 H.sub.9 and C.sub.6 H.sub.5, with ##STR6## wherein X is a halogen.
A copoly(arylene ether) containing pendent ethynyl or substituted ethynyl groups prepared by reacting a mixture of a bisphenol containing an ethynyl or substituted ethynyl group and having the structure ##STR7## wherein R is selected from the group consisting of hydrogen, n,C.sub.4 H .sub.9 and C.sub.6 H.sub.5, and a bisphenol having no ethynyl or substituted ethynyl groups having the structure ##STR8## with ##STR9## wherein X is a halogen.
