| 525447000 | Solid polymer derived from polycarboxylic acid or derivative and a polyhydroxy compound derived from reactant containing ethylenic unsaturation | 6 |
| 20120283392 | POLYESTER PROCESS - The present disclosure provides processes for the preparation of unsaturated polyesters. In embodiments, a process of the present disclosure includes reacting an organic diol with a cyclic alkylene carbonate in the presence of a first catalyst to thereby form a polyalkoxy diol, optionally adding thereto a further amount of cyclic alkylene carbonate in the presence of a second catalyst, and subsequently polycondensing the resulting mixture with a dicarboxylic acid in combination with an anhydride. | 11-08-2012 |
| 20120322950 | BRANCHED POLYESTERS WITH SULFONATE GROUPS - Branched polyesters with sulfonate groups can be obtained by reacting components A, B, optionally C, and optionally D to yield branched polyesters, then reacting these branched polyesters with hydrogen sulfite. Component A is at least one α,β-olefinically unsaturated dicarboxylic acid, component B is at least one di- or higher-functional alcohol, optional component C is at least one di- or higher-functional carboxylic acid or hydroxycarboxylic acid without an α,β-olefinically unsaturated bond, and optional component D is at least one compound of formula CH | 12-20-2012 |
| 20130150533 | BIODEGRADABLE SHAPE MEMORY POLYMER - A shape-memory polymers comprising at least one monomer subunit represented by the following structural formula (1). | 06-13-2013 |
| 20130211013 | ACCELERATOR SOLUTION AND PROCESS FOR CURING CURABLE RESINS - Solution suitable for accelerating the cure of a curable resin using a peroxide, said accelerator solution comprising (i) at least one organic solvent, (ii) a manganese salt, a copper salt, or a combination thereof, and (iii) an iron complex of a tetradentate, pentadentate or hexadentate nitrogen donor ligand. | 08-15-2013 |
| 20140357808 | Process For Preparing A High Molecular Weight Heteroaromatic Polyester Or Coplyester - A process for preparing a high molecular weight heteraromatic polyester or copolyester is disclosed. A process for preparing a high molecular weight heteroaromatic polyester or copolyester includes the steps of: (a) processing comonomers by mixing together to form a homogeneous solution (1) at least one heteroaromatic dicarboxylic acid having 2-12 carbon atoms or a diester or an acid anhydride derived therefrom, or a mixture thereof; (2) at least one alcohol having 2 to 12 carbon atoms and at least two hydroxyl functionalities; and (3) optionally aromatic or aliphatic dicarboxylic acids or diesters or acid anhydrides derived therefrom; (b) converting the paste/solution obtained in step a) into an esterification product containing at least one diester or at least one oligoester formed from the at least one heteroaromatic dicarboxylic acid and the at least one alcohol; and (c) polycondensing/copolycondensing the reaction product obtained from step b) under reduced pressure. | 12-04-2014 |
| 20160096918 | CURABLE COMPOSITIONS - The present invention relates generally to accelerators for the curing of thermosetting resins in the presence of metal compounds, quaternary ammonium and/or phosphonium salts, tertiary amines and/or phosphines and peroxide initiators, and methods of curing thermosetting resins using these accelerators. | 04-07-2016 |
