| abstract |
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. |
