volume permeability

The high gas permeability of PMSP results primary from substantial gas solubility and diffusivity, which appears to be due to, in turn, to a large excess free volume in the unrelaxed ( Iangmuir) domains of this glassy polymer.

PTMSP的高透气性主要来源于极高的对气体溶解度及高扩散系数，而这是因为在这种玻璃态聚合物中，有大量处于非松弛区域的自由体积。
