The Highest Gas Permeable Membranes of Poly[1-(Trimethylsilyl)-1-Propyne] — Their Gas Permeability and Modification

  • Tsutomu Nakagawa


The industrialization of polymeric membrane processes has grown rapidly since the 1970’s because of an increase in our commercial needs. The development of new membrane materials has been expected produce both high permeability and high selectivity. Masuda’s group reported the excellent permeability for gases in a poly[l-(trimethylsilyl)-l-propyne] (PMSP, PTMSP) membrane in 1983.1 Now, PMSP membrane is the highest gas permeable membrane of all synthetic membranes.
