Synthesis of a A2B3-type Hyperbranched Copolymers Based on a 3-Armed Unimolecular 4-N-Methylbenzamide Pentamer and Poly(propylene oxide)

A novel hyperbranched copolymer (HBCP), with a number-average molecular weight from 11000 to 25000, was successfully prepared by the direct condensation polymerization of a unimolecular 3-armed 4-N...
