| 20080287622 | Polymerization of acrylic polymers in reactive diluents - The present process is directed to preparation of addition polymers in diluents that are subsequently reactive in coatings during cure, instead of in traditional hydrocarbon solvents. The polymers so prepared can be used as the main film-forming polymer in high solids coating compositions, especially those useful for finishing automobiles and truck exteriors. | 11-20-2008 |
| 20090143555 | COPOLYMERS COMPRISING TRIMETHYLENE CARBONATE AND POLY(TRIMETHYLENE ETHER) GLYCOLS - The present invention relates to novel copolymers comprising unsubstituted or R-substituted trimethylene carbonate and poly(trimethylene ether)glycol. The copolymers find use in areas including personal care, coatings and lubricants. | 06-04-2009 |
| 20090143562 | PROCESS TO MAKE POLY(TRIMETHYLENE CARBONATE) GLYCOL - This invention relates to the production of poly(trimethylene carbonate) glycol via the polymerization of trimethylene carbonate employing one or more acidic ion exchange resin catalysts in the presence of a solvent. The products formed are substantially free of these catalysts. | 06-04-2009 |
| 20090143563 | HYDROTALCITE CATALYZED POLYMERIZATION OF TRIMETHYLENE CARBONATE - The present invention relates to the use of hydrotalcites as catalysts for the polymerization of unsubstituted or substituted trimethylene carbonate. | 06-04-2009 |
| 20090143564 | PROCESSES FOR THE POLYMERIZATION OF TRIMETHYLENE CARBONATE TO POLY(TRIMETHYLENE GLYCOL CARBONATE TRIMETHYLENE GLYCOL ETHER) DIOL - This invention relates to solventless processes for the polymerization of an unsubstituted or substituted trimethylene carbonate to an unsubstituted or substituted poly(1,3-propanediol carbonate 1,3-propanediol ether)diol, using one or more solid acid catalysts. | 06-04-2009 |
| 20090143624 | COMPOSITIONS OF AND PROCESSES FOR PRODUCING POLY(TRIMETHYLENE GLYCOL CARBONATE TRIMETHYLENE GLYCOL ETHER) DIOL - This invention relates to compositions of and processes for producing an unsubstituted or R-substituted poly(trimethylene glycol carbonate trimethylene glycol ether)diol. The processes use acidic ion exchange resins and include solvents. | 06-04-2009 |
| 20110060116 | PROCESS FOR THE SYNTHESIS OF FLUORINATED ETHERS OF AROMATIC ACIDS - New fluorinated ethers of aromatic acids and diesters are disclosed. These compositions can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved. | 03-10-2011 |
| 20110213118 | POLYARAMID COMPRISING FLUOROVINYLETHER FUNCTIONALIZED AROMATIC MOIETIES - The invention is directed to polyaramid polymers, comprising repeat units of the condensation product of a fluorovinylether functionalized aromatic diacid chloride and an aromatic diamine, and methods to make said polyaramid polymers. The polymers of this invention are useful as high strength fibers or solution cast films with reduced surface susceptibility to oil. | 09-01-2011 |
| 20110213166 | FLUORINATED 4-OXO-CHROMAN-7-CARBOXYLATES - The present invention is directed to compositions comprising fluorinated 4-oxo-chroman-carboxylates, particularly fluorinated 4-oxo-chroman-7-carboxylate, and a process for making the same. The compounds are useful as intermediates in the production of agricultural chemicals, and also as chain terminators in condensation polymerization reactions, particularly when it is desired to provide a polymer having a relatively low surface energy. | 09-01-2011 |
