  • Water-soluble block copolymers comprising a hydrophilic block and a hydrophobic block
    Patent number: 6437040
    Abstract: The invention relates to water-soluble block copolymers comprising at least one block of hydrophobic nature and at least one block of hydrophilic nature, the block of hydrophobic nature exhibiting hydrophilic units in an amount of between 33% and 99% by weight with respect to the total weight of the units of the hydrophobic block. These copolymers are preferably diblocks or triblocks and are prepared by a polymerization process referred to as a living or controlled. Control of their hydrophilic-lipophilic balance makes it possible to adjust their solubility in water and their self-association properties. These copolymers can be used in particular as adhesion agents or wetting agents.
