title = "Synthesis and characterization of novel amphiphilic helical copolymer",
abstract = "The new comb-copolymers [polyacetylene-MPEG (polyethylene glycol monomethyl ether)] were synthesized with (nbd)Rh+[η6-C 6H5B-(C6H5)3] as catalyst. The copolymers with moderate molecular weights (Mn) (13000-170000) and yields (31.6-47.3\%) exhibited higher optical activities compared with chiral monomer, which accorded with the {"}Chiral Amplification{"} effect. The optical activity of the copolymers gradually decreased as the amount of MPEG increased. The maximum amounts of MPEG for successful copolymerization and optical activity of copolymers were 40\%, 30\%, 20\%(mol\%) as the Mn of MPEG was 350, 750, 1900, respectively. The optical activity of copolymers could change at external environmental stimulation, e.g., decreased as methanol content increased.",
