  • Patent number: 8071710
    Abstract: The manufacture of polyetherquinoxalines may be accomplished by polymerization of quinoxaline and related monomers with a bisphenol under aromatic nucleophilic substitution reaction conditions. A method of manufacture includes contacting a substituted or unsubstituted quinoxaline having replaceable groups at the 2,3 positions with a bisphenol or a bisphenol derivative under aromatic nucleophilic substitution reaction conditions. The resulting polyetherquinoxalines contain quinoxaline groups joined by ether linkages at the 2 and 3 positions of the quinoxaline groups. In one example, the polyetherquinoxaline has a formula represented as wherein “n” is an integer from 1 to 10000, and R1, R2, R3, R4 are independently hydrogen, methyl, CF3, tert-butyl, benzoyl, benzenesulfonyl, a sulfonic acid salt, an aliphatic group, an alicyclic group, or an aryl group, and Ar is an aromatic radical.

  • Patent number: RE43880
    Abstract: This invention relates to the composition and a solvent-free process for preparing novel imide oligomers and polymers specifically formulated with effective amounts of a dianhydride such as 2,3,3?,4-biphenyltetra carboxylic dianydride (a-BPDA), at least one aromatic diamine and an endcapped of 4-phenylethynylphthalic anhydride (PEPA) or nadic anhydride to produce imide oligomers that possess a low-melt viscosity of 1-60 poise at 260-280° C. When the imide oligomer melt is cured at about 371° C. in a press or autoclave under 100-500 psi, the melt resulted in a thermoset polyimide having a glass transition temperature (Tg) equal to and above 310° C. A novel feature of this process is that the monomers; namely the dianhydrides, diamines and the endcaps, are melt processable to form imide oligomers at temperatures ranging between 232-280° C. (450-535° F.) without any solvent.
