Abstract: front page image
(EN)A hydrocarbon polymer modifier (HPM) having high softening point and high aromaticity, is an interpolymer of (i) a piperylene component; (ii) an aromatic component; and (iii) a cyclic pentadiene component comprising a dicyclopentadiene fraction (DCPD fraction) and a dimethylcyclopentadiene fraction (MCPD fraction), wherein a weight ratio of the MCPD fraction to the DCPD fraction is from 0.8 to 20, and wherein the MCPD fraction is at least 20 wt% of the cyclic pentadiene component. In a method, the proportions of (i), (ii), (iii), and an optional amylene component are adjusted to control aromaticity, softening point and Mz of the HPM. An elastomeric composition incorporates the HPM.
(FR)Selon l'invention, un modificateur polymère hydrocarboné (HPM, hydrocarbon polymer modifier) de point de ramollissement élevé et d'aromaticité élevée est un interpolymère de (i) un composant pipérylène ; (ii) un composant aromatique ; et (iii) un composant pentadiène cyclique comprenant une fraction dicyclopentadiène (fraction DCPD) et une fraction diméthylcyclopentadiène (fraction MCPD), où un rapport massique de la fraction MCPD sur la fraction DCPD est compris entre 0,8 et 20, et où la fraction MCPD constitue au moins 20 % en masse du composant pentadiène cyclique. Dans un procédé, les proportions de (i), (ii), (iii) et d'un composant amylène éventuel sont ajustées pour maîtriser l'aromaticité, le point de ramollissement et la masse moléculaire Mz du HPM. Une composition élastomère incorpore le HPM.
