Summary:A blended composition of unsaturated block copolymer with improved thermal stability and processing behavior includes at least one unsaturated block copolymer; and a compatibilizer selected from the group consisting of (1) high melt flow rate homopolymers or copolymers; (2) styrene-ethylenepropylene-styrene (SEPS); (3) ethylene vinyl acetate (EVA); (4) styrene- butadiene- styrene (SBS), or styrene-isoprene-styrene (SIS) block copolymers; (5) single site catalyzed polyolefins, such as metallocene catalyzed and constrained geometry polyolefins; (6) amorphous poly alpha olefin homopolymer and copolymers; and (7) a combination of such. L'invention concerne une composition mélangée de copolymères blocs non saturés à stabilité thermique et à aptitude au traitement améliorées qui comprend au moins un copolymère bloc non saturé, et un agent de compatibilité sélectionné dans le groupe comprenant : (1) homopolymères ou copolymères à indice de fluidité élevé ; (2) styrène-éthylènepropylène-styrène (SEPS) ; (3) éthylène acétate de vinyle (EVA) ; (4) copolymères blocs styrène-butadiène-styrène (SBS), ou styrène-isoprène-styrène (SIS) ; (5) polyoléfines catalysées à site unique, de type polyoléfines à géométrie limitée et à catalyse métallocène ; (6) homopolymères et copolymères de poly-alpha-oléfines amorphes ; et (7) une combinaison de ces derniers.
