These macromolecules are composed of a central initiator molecule having one or more hydroxyl groups, which groups under formation of an initial tree structure are bonded to carboxyl groups of a monomeric chain extender. The dentritic macromolecule can be further extended by a reaction with a chain stopper.
- the core materials used are polyols, such as trimethylolpropane, ditrimethylopropane and pentaerythritol.
- the examplified monomeric chain extender is dimethylolpropionic acid.
