Dendritic aliphatic polyesters, highly

The chosen ABj monomer for the synthesis of die dendritic aliphatic polyesters Dl, D2, and D3 was bis-MPA. In the convergent growth approach, dendrons of certain generations were initially synthesized. In a final step these dendrons were coupled to the polyfunctional core molecule (see Scheme 2). To get an acceptable overall yield it is important that all reactions such as coupling, protection, and deprotection are selective and proceed in high yields since a laige number of steps are involved in the synthesis of the final dendrimers. 

Dendritic polyester pol ls The dendritic polyester polyols are one of the specific categories of aliphatic polyester polyols that have high functionality and relatively low viscosity as compared to other polyester polyols. Several grades of these polyester polyols are commerdally available.
