Patent

CA 2496989

The instant invention relates to a composition of a thermoplastic polymer and a triblock-copolymer or grafted comb copolymer, with enhanced melt flow during processing. Further aspects of the invention are the triblock-copolymers or grafted comb polymers itself, a method for their production and their use as compatibilizers and meltflow enhancing additives. Yet another aspect of the invention are functional alkoxyamines, which are useful for the preparation of the triblock-copolymers or grafted comb polymers.

Cette invention a trait à une composition à base de polymère thermoplastique et de polymère tri-séquencé ou de polymère en peigne greffé, laquelle composition fait montre d'une fluidité accrue en cours de traitement. D'autres volets de l'invention portent sur des polymères tri-séquencés ou sur des polymères en peigne greffés, sur un procédé de production de ceux-ci ainsi que sur leur utilisation comme agents de compatibilisation et additifs permettant d'augmenter la fluidité. En outre, un autre volet concerne des alkoxyamines fonctionnelles qui se révèlent des plus utiles s'agissant de la préparation de polymères tri-séquencés ou de polymères en peigne greffés.
