20130079479 | CATALYSIS OF CROSS-LINKING - Disclosed is use of catalysts for chain extension and/or cross-linking of oligomers or polymers comprising carbon-carbon triple bonds. | 03-28-2013 |
20130096256 | NOVEL CROSS-LINKER - Disclosed are novel cross-linkable end-cappers for oligo-and polyimides. End-capped oligo-and polyimides comprising such an end-capper may be cured at a lower temperature compared to oligo-and polyimides end-capped with PEPA. | 04-18-2013 |
20130225769 | CROSS-LINKER - Disclosed are novel cross-linkable end-cappers for oligo- and polyamides. End-capped oligo- and polyamides comprising such an end-capper may be cured at a lower temperature compared to oligo- and polyamides end-capped with PEPA. | 08-29-2013 |
20140018460 | COMPOSITIONS FOR IMPROVING POLYESTERS - A method for altering the melt characteristics of a polyester, such as the melt strength, the method comprising the step of melt mixing the polyester, with a tetracarboxylic dianhydride; across-linker and chain extender comprising at least two groups being able to react with a carboxy group and a phenolic hydroxyl group; and a poly functional compound comprising at least two groups selected from the group consisting of non-sterically hindered phenolic hydroxyl groups, and carboxy groups. | 01-16-2014 |
20140135448 | OLIGO- AND POLYIMIDES - An oligo- or polyimide comprising one or two residue(s) of an anhydride based acetylenic end-capper, at least one EBPA residue, at least one residue of anaromatic di-amine, and optionally at least one residue of an aromatic non-acetylenic di-anhydride is disclosed. A method for obtaining such an oligo- or polyimide is also disclosed. | 05-15-2014 |
20140303328 | CROSS-LINKER - Disclosed are novel cross-linkable end-cappers for oligo- and polyamides. End-capped oligo- and polyamides comprising such an end-capper may be cured at a lower temperature compared to oligo- and polyamides end-capped with PEPA. | 10-09-2014 |
20150080586 | PROCESS FOR PRODUCING (ETHYNE-1,2-DIYL)BIS(ISOBENZOFURAN-1,3-DIONE) - A process for obtaining (ethyne-1,2-diyl)bis(isobenzofuran-1,3-dione) is disclosed. In the disclosed process chloro-, bromo-, or iodoisobenzofuran-1,3-dione is reacted with ethyne in a solvent in the presence of a dissolved homogenous palladium catalyst, optionally a copper salt, a base, and optionally a solvent distinct from said base. Subsequently the obtained (ethyne-1,2-diyl)bis(isobenzofuran-1,3-dione) may be washed with a washing agent, such as a carboxylic acid, a polar aprotic solvent, or chloroform. | 03-19-2015 |
