The present invention provides branched water-soluble polymers that allow two or more water-soluble polymers to be conjugated to another species. The branched polymers provide access to therapeutic agents that are conjugated at a single site to two or more water-soluble polymers. The branched polymers are based upon branch points that are simple branched alkyl structures, reactive side-chain amino acids and small peptides of reactive side-chain amino acids, and saccharides. Also provided is a method for preparing mono-disperse poly(ethylene glycol) of a well-defined and determinable molecular weight, and a method for the rational end-functionalization of poly(ethylene glycol). Conjugates of the branched water-soluble polymers with diverse species, e.g., peptides, lipids, glycolipids and small molecules are also provided.

L'invention concerne des polymères hydrosolubles ramifiés permettant de conjuguer au moins deux polymères hydrosolubles à une autre espèce. Les polymères ramifiés permettent d'obtenir des agents thérapeutiques conjugués au niveau d'un site unique à au moins deux polymères hydrosolubles. Les polymères ramifiés sont édifiés sur des points de ramification, soit des structures d'alkyle simples ramifiées, des acides aminés à chaîne latérale réactive et des petits peptides de ceux-ci, ainsi que des saccharides. L'invention concerne également un procédé de préparation d'un poly(éthylène glycol) mono-dispersé d'un poids moléculaire bien défini et déterminable, ainsi qu'un procédé de fonctionnalisation terminale rationnelle de poly(éthylène glycol). L'invention concerne enfin des conjugués des polymères hydrosolubles ramifiés avec diverses espèces, par exemple, des peptides, des lipides, des glycolipides et des petites molécules.
