Enzyme-catalyzed ring-opening polymerization of ?-propiolactone

Autor: Kazunobu Toshima, Shuichi Matsumura, Hideki Beppu, Keisuke Tsukada

Publikováno v: Biotechnology Letters. 18:1041-1046

β-Propiolactone (BPL) was polymerized in bulk using lipase as a catalyst to form the polyester having a molecular weight of greater than 50000. The molecular weight of the polyesters produced by the lipase-catalyzed polymerization of BPL was inverse

Direct numerical simulation of a turbulent flow in a channel having periodic pressure gradient

Autor: Yutaka Miyake, Hideki Beppu, Koichi Tsujimoto

Publikováno v: International Journal of Heat and Fluid Flow. 16:333-340

The intent of this paper is to contribute database information for a flow less complicated than a backward step flow and less simple than a flat channel flow, demonstrating the influence of pressure gradient in an internal flow and serving to stimula

Enzymatic Preparation of Malate-Based Polycarboxylates Having Higher Molecular Weights by Copolymerization with Lactone

Autor: Hideki Beppu, Kazunobu Toshima, Shuichi Matsumura

Publikováno v: Chemistry Letters. 28:249-250

A strategy for increasing the molecular weight of malate-based polycarboxylates by the enzymatic polymerization of benzyl β-malolactonate (BML) with organic additives was studied. The lipase-catalyzed ring-opening polymerization of BML was significa

Preparation of Poly(β-malic acid) by Enzymatic Ring-Opening Polymerization of Benzylβ-Malolactonate

Autor: Kazuhiro Nakamura, Hideki Beppu, Shuichi Osanai, Kazunobu Toshima, Shuichi Matsumura

Publikováno v: Chemistry Letters. 25:795-796

Poly(β-malic acid) was prepared by lipase-catalyzed ring-opening polymerization of benzyl β-malolactonate with subsequent debenzylation. Benzyl β-malolactonate was readily polymerized by porcine pancreatic lipase or Novozyme 435 lipase at 60 °C t
