  • feasibility study on continuous Flow controlled living anionic polymerization processes
    Organic Process Research & Development, 2016
    Co-Authors: Aiichiro Nagaki, Yuichi Nakahara, Mai Furusawa, Tomoya Sawaki, Tetsuya Yamamoto, Hideaki Toukairin, Shinsuke Tadokoro, Toshiya Shimazaki, Toshihide Ito, Masakazu Otake
    Abstract:

    A practical microchemical reaction system for keeping process Flow at defined conditions, which is one of the key issues of industrial production, was developed. Controlled/living anionic polymerization was chosen as a test reaction because the molecular weight and molecular weight distribution of polymer products are quite sensitive to the Relative Flow Rate of an initiator solution and that of a monomer solution. The polymerization of styrene in THF/hexane was carried out using a Flow microreactor system consisting of two T-shaped micromixers and two microtube reactors using SmoothFlow pumps at 0 °C. Poly(styrene) with higher molecular weight such as Mn > 10000 could be synthesized using s-BuLi (Mn = 14 000, Mw/Mn = 1.11). n-BuLi could also be used as an initiator. The continuous operation was performed for 3 h without any problems to obtain ca. 1 kg of the polymer, indicating the feasibility of continuous Flow processes for controlled/living anionic polymerization on a Relatively large scale.
