Abstract
Organic-inorganic hybrid polyaspartimide polymers were synthesized via Michael addition by using octa(aminophenyl)silsesquioxane (OAPS) (2.5-30 wt %), leading to a family of porous polymers. The formation of -NH structure during Michael addition assists in CO 2 capture. The CO 2 capture capacity increased with increasing concentration of OAPS from 2.5 to 25 wt % in the PAI/OAPS polymers.
