Abstract
There is provided a composition comprising: (i) a hyperbranched polymer having peripheral reactive groups comprising epoxy functional groups and hydroxyl functional groups; and (ii) a compound having one or more hydrophilic functional groups, wherein the amount of epoxy functional groups relative to the total number of peripheral reactive groups does not render the hyperbranched polymer from being indispersible in an aqueous solvent. There is also provided a method of preparing the same and uses thereof.
