Title (EN) METHOD OF PREPARING A GRAFTED COPOLYMER OF LIGNIN AND/OR CELLULOSE
(FR) PROCÉDÉ DE PRÉPARATION D'UN COPOLYMÈRE GREFFÉ DE LIGNINE ET/OU DE CELLULOSE
Abstract: front page image
(EN)The present invention relates to a method of preparing grafted copolymers of lignin and/or cellulose, comprising the generation of macroradicals in situ by mechanical impact on the backbone of said lignin and/or cellulose of said lignin and/or cellulose containing material and grafting monomers and/or polymers to said backbone. Furthermore, the present invention relates to the grafted copolymers obtainable by said method, composite materials comprising said copolymers as well as to uses thereof.
(FR)La présente invention concerne un procédé de préparation de copolymères greffés de lignine et/ou de cellulose, comprenant la génération de macro-radicaux in situ par impact mécanique sur le squelette de ladite lignine et/ou cellulose dudit matériau contenant de la lignine et/ou cellulose et la greffe de monomères et/ou polymères audit squelette. En outre, la présente invention concerne les copolymères greffés pouvant être obtenus par ledit procédé, des matériaux composites comprenant lesdits copolymères ainsi que leurs utilisations.
