Abstract : High molecular weight enyne polysulfone thermoplastics are prepared by the reaction of alkali metal salts of 1,4-bis(3-hydroxyphenyl)-buta-l-ene-3-yne and various aromatic diols with aromatic dihalosulfones. Because of the presence of the enyne moiety in the polymer backbone, the polymer can be lightly crosslinked to provide solvent resistant thermoplastics. The polymers are useful in fabricating graphite thermoplastic composites for structural applications.
