| titleOfInvention | Method for preparing copolymers of alkyl methacrylate and maleic anhydride |
| abstract | A method for preparing a sulfur-free copolymer comprising units of the alkyl methacrylate monomer and units of the maleic anhydride monomer, by dissolving polymerization of one or more alkyl methacrylates and maleic anhydride in a solvent in the presence of a radical initiator, comprising said method the steps of a) providing an initial reaction solution comprising a part of the one or more alkyl methacrylates, a part of the maleic anhydride, a part of the initiator and a part of the solvent; b) adding a first feed solution comprising an additional part of the maleic anhydride and an additional part of the solvent, to the initial reaction solution, and without any initiator; and c) adding a second feed solution comprising an additional part of the one or more alkyl methacrylates and a portion of the radical initiator to the initial reaction solution, wherein the additions of both the first and second feed solutions are they start at the same time, and the duration of the additions of the first and second feed solutions are adjusted so that the addition of the first feed solution is completed faster than the addition of the second feed solution 15, and where The sulfur-free copolymer has a number average molecular weight of 3000 to 9000 g / mol, the number average molecular weight being determined by gel permeation chromatography against poly (methyl methacrylate) standards and a polydispersity index in the range of 1 to 5, determining the polydispersity index by gel permeation chromatography versus poly (methacryl) patterns methyl can), and wherein the molar ratio of one or more alkyl methacrylates to maleic anhydride in the sulfur-free copolymer is in the range of 10: 1 to 1: 1, based on the total molar amounts of one or more alkyl methacrylates and maleic anhydride, used for the preparation of the sulfur-free copolymer. |
