Abstract
The present disclosure relates to a composition comprising: at least one dendritic polymer prepared from hyper-branched polymer with hydroxyl groups, having a plurality of peripheral functional groups, wherein the peripheral functional groups comprising at least one cyclic ether group that is covalently bound to said hyperbranched polymer by urethane linkages; and a melamine-based crosslinker. Such compositions have improved flexibility. The present disclosure further relates to the use of such compositions to form coatings after cure, or as an additive component to binder resins.
