Abstract

Two series of new 3-arm AE2, 4-arm ABE2, 5-arm ABCE2, and 5-arm AD2E2, 6-arm ABD2E2, 7-arm ABCD2E2 asymmetric star-branched polymers have been synthesized using living anionic polymers and 3, 5-bis (3-(4-(1-phenylethenyl) phenyl) propoxy) benzyl bromide. The A, B, C, D, and E arms were polystyrene (A), poly (α-methylstyrene)(B), poly (4- methoxystyrene)(C), poly (4-trimethylsilylstyrene)(D), and poly (4-methylphenylvinyl ...
