Title (EN) A POLYMER/CLAY NANOCOMPOSITE AND PROCESS FOR THE PRODUCTION THEREOF
(FR) NANOCOMPOSITE POLYMERE/ARGILE ET PROCEDE D'OBTENTION
Abstract: front page image
(EN)The present invention discloses a copolymer/clay composite and process for the production thereof, in which the copolymer is based on at least two monomers selected from the group consisting of butadiene ,isoprene and styrene .The above composite is prepared by conventional anionic solution polymerization process with alkyl lithium as initiator, organic hydrocarbon as solvent and polar additive as microstructure modifier, in which at least two monomers selected from the group consisting of butadiene ,isoprene and styrene achieve in-situ intercalation polymerization in the presence of organoclay. The above exfoliated-clay nanocomposite exhibits excellent mechanic property, heat resistance, gas barrier property, chemical resistance and excellent balance in all kinds of properties.
(FR)La présente invention concerne un composite copolymère/argile et son procédé d'obtention, le copolymère comprenant au moins deux monomères pris dans le groupe comprenant butadiène, isoprène et styrène. Le composite susmentionné s'obtient par un processus de polymérisation d'une solution anionique classique avec de l'alkyl lithium comme initiateur, un hydrocarbure organique comme solvant et un additif polaire comme modificateur de microstructure, procédé dans lequel au moins deux monomères choisis dans le groupe comprenant butadiène, isoprène et styrène réalisent une polymérisation d'intercalation in situ en présence d'argile organique. Le nanocomposite d'argile exfolié est remarquable en termes de caractéristiques mécaniques, de résistance à la chaleur, de capacité à arrêter des gaz, de résistance chimique et d'équilibre entre toutes les propriétés susmentionnées.
