## Abstract A novel hyperbranched polymer (**3**) was prepared by copolymerization of tri‐aldehyde moieties with azo chromophores having two active methelene groups, from "A~2~+B~3~" approach based on simple Kneovenagel reaction. For comparison, its analogue linear polymer (**5**) was also synthesi
