| titleOfInvention | Method for synthesizing a thermoplastic elastomer comprising at least one poly(α-methylstyrene) block |
| abstract | A method for synthesizing a thermoplastic elastomer comprising at least one polydiene block and at least one other poly(α-methylstyrene) block comprises:n polymerizing at least one diene monomer in a starting reaction medium comprising an anionic polymerization initiator and an aprotic non-polar solvent; polymerizing α-methylstyrene to the living polydiene chain obtained in the preceding step comprising: maintaining the reaction medium containing the living diene elastomer obtained previously and α-methylstyrene at a positive temperature, below the ceiling temperature for the polymerization of α-methylstyrene; cooling the reaction medium obtained at the end of step a., to a temperature below 0° C.; simultaneously, successively or prior to the cooling step, adding a purified aprotic polar solvent to the reaction medium with a volume ratio of the polar solvent to the non-polar solvent of less than 1; and propagating the polymerization of α-methylstyrene to the living polydiene chain. |
