摘要

正

Optically active copolymers of pairs of three monomers

triphenyl （methyl methacrylate）and one or two pyridyl substituted methyl methacrylate homologues

were obtained by helix-sense-selective copolymerization using complexes of organolithium with chiral ligand as anionicinitiators in toluene at low temperature. The copolymers obtained with （-）-sparteine （Sp） and（S

S）-（+）-and （R

R）-（-）-2

3-dimethoxy-1

4-bis （dimethylamino） butanes（（+）-and （-）-DDB） complexes of organolithium showed low optical activity

but PMP complex with N

N-diphenylethyleneamine monolithium amide （PMP-DPEDA-Li） was effective in synthesizingcopolymers of high optical rotation ([α]

about+320～1370°)which were comparable to thoseof relative homopolymers with one-handed helical structure.
