Diffusion and solution of gases in substituted polyacetylene membranes
The coefficients of permeability, diffusion and solubility ( P, D and S, respectively) of various substituted polyacetylenes for six gases (He, H 2, O 2, N 2, CO 2 and CH 4) at 25°C were determined. The polyacetylenes with a bulky substituent such as poly[1-(trimethylsilyl)-1-propyne] (poly(TMSP)) g...

| description | The coefficients of permeability, diffusion and solubility (
P,
D and
S, respectively) of various substituted polyacetylenes for six gases (He, H
2, O
2, N
2, CO
2 and CH
4) at 25°C were determined. The polyacetylenes with a bulky substituent such as poly[1-(trimethylsilyl)-1-propyne] (poly(TMSP)) generally exhibited large
P values. The especially large
P values (∼ 2 × 10
3−2 × 10
4 barrer) of poly(TMSP) were found to be based on both its
D and
S values being large. The polyacetylenes with a long
n-alkyl group showed fairly large
D values, while those with a phenyl group had relatively large
S values. The activation parameters for
P,
D and
S (
E
P,
E
D and
ΔH
S, respectively) were obtained from their temperature dependences (30–70°C). The
E
P values of poly(TMSP) were all negative (−9.7 to −0.4 kJ mol
−1). This stemmed from its small
E
D values compared with those of other polymers. |
