The copolymerizations of (S)-1,3-butanediyl and (2S,4S)-2,4-pentanediyl bis(4-vinylbenzoate)s (1a and 1b) (M(1)) with styrene (M(2)) were carried out using AIBN in toluene at 60 degrees C. The obtained copolymers (2) consisted essentially of the cyclic repeating and styrene units, because the characteristic absorption due to the vinyl protons disappeared in the H-1-NMR spectre. The copolymerization reactivities of la and Ib were higher than that of styrene, resulting in the mole fraction of the M(1) unit in the copolymer 2 being higher than that of the M(2) unit for every monomer feed. The monomer reactivity ratio, which was calculated by the Kelen-Tudos method, was r(1) = 4.39 and r(2) = 0.20 for 1a and r(1) = 3.81 and r(2) = 0.28 for 1b. The specific rotation ([alpha](435), c 1.0 in CHCl3) changed from +283 degrees to +182 degrees for 2a and from +434 degrees to +319 degrees for 2b. After removing the chiral templates from 2a and 2b, poly[(methyl 4-vinylbenzoate)-co-styrene]s (3a and 3b) were obtained. The specific rotation ([alpha](435), c 1.0 in CHCl3) varied from -0.5 degrees to -24.0 degrees for 3a and from -0.4 degrees to -46.3 degrees for 3b, which indicated that, the (2S,4S)-2,4-pentanediyl template approximately doubled in effect for the asymmetric induction by comparison with the (S)-1,3-butanediyl one. A split Cotton effect with a negative Cotton effect and a positive one was observed for the CD spectrum of 1 and the reversed one for 3. According to the CD exciton chirality method, the clockwise twist of the two 4-vinylbenzoates of 1 transmitted their chirality to 3 in which two 4-vinylbenzoyl groups twisted counterclockwise, i.e., an (R,R)-configuration of vicinal (methyl 4-vinylbenzoate) units in the main chain.
