ABSTRACT:
A chain extended dendritic polyether comprising a dendritic core polymer and a chain extension bonded to said core polymer, which chain extended dendritic polyether optionally is at least partially chain terminated and/or partially functionalised. The core polymer is a polyhydric dendritic polyether and the chain extension is obtained by addition of at least one alkylene oxide to at least one hydroxyl group in said core polymer.
