Title
(EN) PROCESSES FOR MAKING LOW VOLATILE TACKIFIER COMPOSITIONS
(FR) PROCÉDÉS DE FABRICATION DE COMPOSITIONS TACKIFIANTES FAIBLEMENT VOLATILES
Abstract
(EN) A tackifier composition comprising at least one thermoplastic hydrocarbon resin and an antioxidant composition is provided; wherein a portion of the volatile organic compounds in the thermoplastic hydrocarbon resin has been removed; wherein the antioxidant composition comprises at least one primary antioxidant and at least one secondary antioxidant; and wherein the levels of individual volatile organic compound monitored in the tackifier composition are less than about 0.5 ppm as measured by GC/MS headspace analysis. Processes for producing the tackifier composition are also provided as well as adhesives comprising the tackifier compositions.
(FR) L'invention concerne une composition tackifiante comprenant au moins une résine hydrocarbonée thermoplastique et une composition antioxydante, une partie des composés organiques volatils dans la résine hydrocarbonée thermoplastique ayant été retirée, la composition antioxydante comprenant au moins un antioxydant primaire et au moins un antioxydant secondaire, et les teneurs de composé organique volatil individuel surveillées dans la composition tackifiante étant inférieures à environ 0,5 ppm telles que mesurées par analyse par espace de tête GC/MS. L'invention concerne également des procédés de production de la composition tackifiante ainsi que des adhésifs comprenant les compositions tackifiantes.
