DENDRITIC MACROMOLECULE, PROCESS FOR PREPARATION THEREOF AND USE THEREOF

摘要

The invention relates to a dendritic macromolecule of the polyester type, which macromolecule is composed of a central initiator molecule or initiator polymer having one or more reactive groups (A), which groups (A) under formation of an initial tree structure are bonded to reactive groups (B) of a monomeric chain extender holding the two reactive groups (A) and (B). The tree structure is potentially extended and further branched from the initiator molecule or initiator polymer by an addition of further molecules of a monomeric chain extender by means of bonding between the reactive groups (A) and (B) thereof and is possibly further extended by a reaction with a chain stopper. The invention also comprises a process for preparation of the dendritic macromolecule.
