| Popis: |
Certain polyacetylenes having spherical substituents are known to exhibit high gas permeability. Poly[1-phenyl-2-(p-trimethylsilyl)phenylacetyllene] (PTMSDPA) is one of such examples, and its oxygen permeability coefficient (PO2) has been reported to be about 1500 barrers. Though poly(1-trimethylsilyl-1-propyne) is known to be most permeable among all the existing polymers, its gas permeability remarkably decreases with time. The purpose of the present study is to elucidate the time dependence of gas permeability of PTMSDPA. The initial values of PO2 and PN2 were determined to be 2200 and 1000 barrers. Further it was clarified that the gas permeability of PTMSDPA hardly changed even after six weeks irrespective of the method of preservation. |
