## Abstract Hyperbranched epoxide‐amine adducts were synthesized by a one‐pot microwave (MW) assisted reaction. 4‐(2,3‐epoxypropyl‐1‐oxy)benzonitrile was hydrogenated using Pd/C under microwave conditions, forming the AB~2~ monomer 1‐aminomethyl‐4‐(2,3‐epoxypropyl‐1‐oxy)benzene. Depending on the re
## Abstract A hyperbranched polyethoxysiloxane was synthesized via hydrolytic polycondensation between methyltriethoxysilane (MTES) and tetraethoxysilane (TEOS), with hydrochloride acid as catalyst. FTIR, ^1^H NMR, ^29^Si NMR, and GPC measurements confirmed that the polyethoxysiloxane synthesized w
