Title
(EN) Dendritic macromolecule and a process thereof
Abstract
(EN)

The present invention is in relation to a dendritic molecule having symmetrically sited branches having four or more generations of dendrimers wherein the branch points are tertiary amines linked together with oxygen atom of ether and the heteroatoms are separated by a substituted or non-substituted linear three methylene linker. In addition the invention also provides a process to prepare such dendritic macromolecules.
