Patent number: 5136011Abstract: The present invention features a highly oriented, triazine superstructural network, whose structural alignment is magnetically induced in the liquid crystalline phase during the curing process of its liquid crystalline cyanate ester precursor. High mechanical strength cross-linked network structures are prepared from a new class of liquid crystalline dicyanate compounds. Optionally ring substituted di-(4-hydroxyphenyl)-terephthalate is synthesized as a precursor in the preparation of highly structured triazine networks. The orientation of the triazine networks has been accomplished by magnetically aligning the liquid crystalline phase of the precursor during the curing reaction.Type: GrantFiled: September 19, 1990Date of Patent: August 4, 1992Assignees: Cornell Research Foundation, International Business Machines CorporationInventors: George G. Barclay, Christopher K. Ober, Konstantinos I. Papathomas, David W. Wang

Patent number: 5116936Abstract: Polyesters or polyanhydrides are produced by reaction of non-conjugated dienes with diols or dicarboxylic acids, respectively, in the presence of a catalyst composition formed from a palladium compound, a monodentate phosphorus ligand optionally employed with a bidentate phosphorus ligand and a limited amount of a protonic acid having a pKa below 2, in the substantial absence of water. The polymer products are useful as constituents of sealants, adhesives and paints.Type: GrantFiled: May 23, 1991Date of Patent: May 26, 1992Assignee: Shell Oil CompanyInventors: Eit Drent, Anthonius J. M. Breed
