Patent ID: 7229574

Claim:
A method for preparing polyaniline graft copolymer represented by Formula (I) which comprises the steps of: reacting aminostyrene (AMS) with di-tert-butyl-carbonate ((BOC)2) to give BOC-AMS; copolymerizing BOC-AMS with sodium styrenesulfonate (SSNa) to give P(SSNa-co-BOC-AMS) of the following formula: eliminating tert-butyl di-carbonate (BOC) from P(SSNa-co-BOC-AMS) to give P(SSA-co-AMS) of the following Formula (II): wherein n is a numerical number from 1–5,000, inclusive, and m is a numerical number of 1–1,000, inclusive; and grafting aniline onto the P(SSA-co-AMS) to give polyaniline graft copolymer of the Formula (I).
