Popis: Basic feature of styrene polymerization under the action of 1,3-bis(1-lithio-1-methylhexyl)-benzene (1) in the presence of tetrahydrofuran were studied. UV spectra of 1 and dilithiumpolystyrene in a benzene solution with an without THF were investigated. A comparison of the results of the UV spectra with the data of cryoscopy and viscometric measurements of “living” and deactivated polystyrene allows the conclusion that polystyrene chains propagating on the dilithium catalyst are in monomeric form.
