Title (EN) THERMOPLASTIC ELASTOMER BASED ON POLYNORBORNENE AND VINYL POLYCHLORIDE
(FR) ELASTOMERE THERMOPLASTIQUE A BASE DE POLYNORBORNENE ET DE POLYCHLORURE DE VINYLE
Abstract:
(EN) The composition of the present invention is comprised of a mixture from 20 to 70 parts by weight of cross-linked polynorbornene, from 80 to 30 parts by weight of a polymer based on vinyl chloride and at least one plastifier common to polynorbornene and to the polymer based on vinyl chloride, in a quantity sufficient to lower the glass transition temperature of polynorbornene down to the range of rubbers. In order to prepare the thermoplastic composition comprising the cross-linked polynorbornene, a blend of polynorbornene, vinyl chloride polymer, a plastifier common to the polynorbornene and to the vinyl chloride polymer and a cross-linking system is mixed at a temperature and time duration sufficient to cross-link the polynorbornene.
(FR) Cette composition comprend un mélange de 20 à 70 parties en poids de polynorbornène, réticulé, de 80 à 30 parties en poids d'un polymère à base de chlorure de vinyle et d'au moins un plastifiant commun au polynorbornène et au polymère à base de chlorure de vinyle, en quantité suffisante pour abaisser la température de transition vitreuse du polynorbornène jusqu'à la gamme des caoutchoucs. Pour préparer la composition thermoplastique comprenant du polynorbornène réticulé, on malaxe un mélange de polynorbornène, de polymère à base de chlorure de vinyle, de plastifiant commun au polynorbornène et au polymère à base de chlorure de vinyle et d'un système de réticulation à une température suffisante et pendant une durée suffisante pour réticuler le polynorbornène.
