Preparation and post-polymerization of telechelic polymer. The telechelic polymer P1a/2a is prepared at a monomer feed ratio of 1:1, and the polymerizations of telechelic P1a/2a with 1a (route I), 1c (route II), and 1d (route III) are conducted based on the apparent monomer-nonstoichiometry-promoted effect.
