摘要：In this work, styrene/butadiene (S/B) copolymer was synthesized via anionic bulk polymerization using a twin-screw extruder as a reactor and butyl lithium as the initiator. The structure of the copolymer was characterized by FT-IR, 1H-NMR, TEM and DMA. It was found that macromolecule structure of prepared copolymer was composed of a long PS block, several short PS and PB blocks. A "bubble theory" was proposed to explain this result.
