| titleOfInvention | METHOD FOR PRODUCING POLYMERS WITH ACID END GROUPS BY RADICAL POLYMERIZATION WITH ATOMIC TRANSFER |
| abstract | 1. A method of producing polymers with acidic end groups, characterized in that the halogen atoms at the ends of the polymer chains are replaced by the addition of the corresponding sulfur compound with an acidic functional group, and to isolate the transition metal compounds by adding the same sulfur compound from the polymer solutions, the transition compound is simultaneously precipitated metal, which is isolated by subsequent filtration. ! 2. A method for producing polymers with acid end groups according to claim 1, characterized in that, in order to simultaneously remove halogen atoms from polymers by adding a sulfur compound, more than 90% of halogen atoms are replaced. ! 3. A method for producing polymers with acidic end groups according to claim 2, characterized in that, in order to simultaneously remove halogen atoms from polymers by adding a sulfur compound, more than 95% of halogen atoms are replaced. ! 4. A method for producing polymers with acid end groups according to claim 3, characterized in that the sulfur compound is a mercaptan or other organic compound containing a mercapto group. ! 5. The method of producing polymers with acid end groups according to claim 4, characterized in that the sulfur compound contains an additional functional group. ! 6. A method for producing polymers with acidic end groups according to claim 5, characterized in that the additional functional group means an acidic group or a group which, under the existing reaction conditions, forms an acidic group. ! 7. A method of obtaining polymers with acidic end groups according to claim 6, characterized in that the sulfur compound means the regulator |
