Synthesis and characterization of a novel alcohol-soluble polyorganosiloxane containing amino side groups

A novel alcohol-soluble polyorganosiroxane containing amino side groups, po ly[3-(4-aminophenoxy)-aminophenoxy) propylmethylsiloxane] (2), was first pr epared by the reduction of nitro groups on 4-nitrophenoxypropyl side chains of poly[3-(4-nitrophenoxy)propylmethylsiloxane] (1). The reaction proceede d easily with nearly 100% conversion. The synthesized alcohol-soluble polym er 2, which has potential application as a precursor for preparing advanced functional polymers, was characterized by FTIR, H-1-NMR, C-13-NMR, Si-29-N MR, VPO and GPC, respectively.
