Patent number: 8119764Abstract: Medical device (?) comprising at least one part (?) consisting of a polymer material (M) comprising at least one kinked rigid-rod polyarylene (P) of which more than 50 wt. % of the recurring units are recurring units (R) of one or more formulae consisting of an optionally substituted arylene group which is linked by each of its two ends to two other optionally substituted arylene groups via a direct C—C linkage. The recurring units (R) are a mix (?) consisting of (i) between 0 and 75 mole %, of rigid rod-forming arylene units (Ra) and (ii) between 25 and 100 mole % of kink-forming arylene units (Rb), both contents being based on the total number of moles of the recurring units (R). Arylene units (Ra) and/or (Rb) may be optionally substituted by at least one monovalent substituting group.Type: GrantFiled: September 9, 2008Date of Patent: February 21, 2012Assignee: Solvay Advanced Polymers, L.L.C.Inventors: Nikica Maljkovic, Bianca Sadicoff Shemper, Mohammad Jamal El-Hibri

Patent number: 8106142Abstract: Polyacetylinic oligomers suitable for high-temperature polymer-matrix composites are provided. The polyacetylinic oligomers have the formula: D-A-D wherein D is an endcap including at least one crosslinking functionality; and A is backbone selected from the group consisting of imidesulfone; ether; ethersulfone; amide; imide; ester; estersulfone; etherimide; amideimide; oxazole; oxazole sulfone; thiazole; thiazole sulfone; imidazole; and imidazole sulfone. At least one ethynyl functional group, however, is incorporated into the backbone such that crosslinking is not only realized at the endcaps but also at the ethynyl groups within the backbone of the oligomer itself.Type: GrantFiled: October 20, 2009Date of Patent: January 31, 2012Assignee: The Boeing CompanyInventors: Thomas K. Tsotsis, Norman R. Byrd

Patent number: RE43880Abstract: 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.Type: GrantFiled: May 8, 2006Date of Patent: December 25, 2012Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventor: Chun-Hua Chuang
