A polymeric amphipathic stabiliser is formed of hydrophobic monomer units and hydrophilic monomer units which comprise carboxylic free acid or acid salts units and glycidyl or anhydride units. The glycidyl or anhydride units react onto reactive groups on polymer particles when dispersed in non-aqueous liquid and provide improved stability when the particles are subsequently dispersed in liquid electrolyte.
On décrit un stabilisant amphiphatique polymère formé d'unités de monomère hydrophobes et d'unités de monomère hydrophiles. Ce stabilisant contient des unités d'acide carboxylique libre ou des unités de sel d'acide et des unités de glycidyle ou d'anhydride. Les unités de glycidyle ou d'anhydride réagissent au contact de groupes réactifs aux particules de polymère lorsqu'elles sont dispersées dans un liquide non aqueux; elles offrent ainsi une stabilité accrue lorsque les particules sont subséquemment dispersées dans un électrolyte liquide.
