Abstract:
(EN) The present invention relates to: a method for preparing a copolymer, comprising a step of injecting and polymerizing a surface-modified silica nano-powder, a vinyl cyanide-based monomer and an aromatic vinyl-based monomer, wherein the surface-modified silica nano-powder is obtained by surface-modifying a silica nano-powder with a chain transfer agent for reversible addition-fragmentation chain transfer polymerization; a copolymer; and a thermoplastic resin molded product and, relates to a method for preparing a copolymer having improved heat shrinkage and reflection haze, the copolymer, and a thermoplastic resin molded product.
(FR) La présente invention concerne : un procédé de préparation d'un copolymère, comprenant une étape d'injection et de polymérisation d'une nano-poudre de silice modifiée en surface, d'un monomère à base de cyanure de vinyle et d'un monomère à base de vinyle aromatique, la nano-poudre de silice modifiée en surface étant obtenue par modification de surface d'une nano-poudre de silice avec un agent de transfert de chaîne pour une polymérisation par transfert de chaîne par addition-fragmentation réversible ; un copolymère ; et un produit moulé en résine thermoplastique et, concerne un procédé de préparation d'un copolymère ayant un retrait thermique et un trouble de réflexion améliorés, le copolymère et un produit moulé en résine thermoplastique.
