查询词典 surveying chain

First, the precursor polymer with azobenzene groups on main-chain was obtained by condensation polymerization between 4,4'-dihydroxyazobenzene and N,N-(2-bromoethyl)aniline through Williamson reaction. Then the azo polymer containing azobenzene groups both on main-chain and side-chain was prepared through an azo-coupling reaction between the precursor polymer and the diazonium salt of 4-nitroaniline.
