Patent number: 8609801Abstract: Polymers and copolymers containing 1H-benzo[d]imidazol-2(3H)-one units have been synthesized under conditions generally used for the synthesis of poly(aryl ether)s. 1H- benzo[d]imidazol-2(3H)-one behaves like a biphenol in the polymerization reaction. The soluble homopolymer has a very high glass transition temperature (348° C.), good thermal stability, and forms flexible transparent films. Because of the low molecular weight (134.14) of the benzoimidazolone monomer in the copolymer formed with 4,4?-biphenol that contains 30 mole % of the benzimidazolone unit, only 8.9 weight % is required to raise the Tg of the poly(arlyl ether)sulfone from 220° C. to 269° C.Type: GrantFiled: September 26, 2012Date of Patent: December 17, 2013Assignee: The Royal Institution for the Advancement of Learning/McGill UniversityInventors: Allan S.
