Title (EN) POLYMER BLEND COMPATIBILIZATION USING ISOBUTYLENE-BASED BLOCK COPOLYMERS
(FR) COMPTABILISATION DE MELANGES POLYMERES AU MOYEN DE COPOLYMERES BLOCS A BASE D'ISOBUTYLENE
Abstract: front page image
(EN)Compatibilized blends of an isobutylene polymer and an unsaturated diene polymer are prepared using a compatibilizing agent comprising a block-graft copolymer containing polyisobutylene segments and C¿4? to C¿6? alkyl-substituted styrene polymer segments, such as poly(t-butylstryrene) segments.
(FR)L'invention concerne des mélanges comptabilisés d'un polymère isobutylène et d'un polymère diène non saturé préparés au moyen d'un agent comptabilisant comportant un copolymère bloc greffé qui comporte des segments polyisobutylène et des segments de polymère styrène à substitution alkyle C4 à C6, tels que des segments poly(t-butylstyrène).
