摘要:
The present invention relates to a method for preparing a hydrophobized biomaterial consisting of a hydrophilic material, in particular chosen from plant fibres, having hydroxyl functions, on which material chains of polymers having ester functions are grafted, said method comprising a step of bringing said hydrophilic material into contact with said polymers and a transesterification reaction between said ester functions and said hydroxyl functions.
