ABSTRACT:
Rod-shaped dendrimers having a plurality of dendritic branches emanating from an essentially linear core are prepared by first reacting a linear polyfunctional core compound such as a polyethyleneimine with a first dendritic branching reactant such as an ester of an unsaturated carboxylic acid, e.g., methyl acrylate, and then successively reacting the resulting product with a second dendritic branching reactant such as ethylenediamine and then with the first or another dendritic branching reactant.
The rod-shaped dendrimers are useful in the production of molecular composites and as crystallinity modifiers for polymeric materials.
