Polyamido polysulfone thermoplastics and intermediates thereof

摘要: Thermoplastic copolymers having both bis-amide moieties and polyarylene bis-sulfone in the recurring structural units of chains are formed by interaction (1) monomers two terminal amideforming groups (2) difunctional compounds amide-forming complementary to those polysulfone monomers. Thus, a diamino monomer is condensed with di-acid chloride or anhydride; or, di-sulfone di(carboacid chloride) an aromatic diamine.
