| titleOfInvention | Process for the preparation of functionalized and branched elastomeric copolymers and their use in vulcanizable elastomeric compositions |
| abstract | A process for preparing functionalized and branched elastomeric copolymers is provided. The method comprises (a) at least one conjugated diene monomer and at least one vinyl in the presence of at least one hydrocarbon solvent, at least one lithium-based initiator, and at least one polar modifier. Anionic copolymerization of arenes to obtain a solution comprising an elastomeric copolymer; (B) at least 10%, preferably 20% to 100% by weight of the polymer chains present in the elastomeric copolymer obtained in step (a), of at least one selected from epoxides, ketones, esters, aldehydes Reacting with at least one compound having a functional group to obtain a solution comprising a functionalized elastomeric copolymer; (C) To the solution obtained in step (b), 1 to 4 times, preferably 1.5 to 3 times the amount of the lithium initiator used in step (a), Formula (I): R-Br (I) (Wherein, R is a linear or branched C 1 -C 30 alkyl group, preferably a linear or branched C 2 -C 10 alkyl radical; C 3 -C 30 cycloalkyl group, preferably a C 4 -C 10 Adding a brominated rod having a cycloalkyl group (representing a C 6 -C 30 aryl group, preferably a C 6 -C 12 aryl group). [Selection figure] None |
