COPOLYMERS WITH WATER-SOLUBLE BLOCKS COMPRISING A HYDROPHOBIC BLOCK AND A HYDROPHILIC BLOCK

摘要

The invention relates to copolymers having water-soluble blocks comprising at least one hydrophobic block and at least one hydrophilic block, said hydrophobic block having a quantity of hydrophilic units of between 33 and 99 wt.- % with respect to the total weight of the hydrophobic block units. The aforementioned copolymers are preferably diblocks or triblocks and are prepared using a living or controlled polymerisation method. The hydrophilic/hydrophobic balance of said copolymers can be controlled in order to modulate the water solubility and self-association properties thereof. Said copolymers are particularly suitable for use as adhesive or wetting agents.
