Abstract

ABSTRACT: Synthesis of polyacetyelenes and investigation of their gas permeation properties strongly influenced membrane material science. Many other highly permeable glassy polymers that belong to different chemical classes have been created and investigated. In many case their design was similar to that of disubstituted polyacetyelenes. Structure and properties of various polymers with SiMe3 side groups are considered in this review. Many of them are characterized by solubility controlled permeation of hydrocarbons like polyacetylenes. An important factor that determines high permeability of all these polymers is large free volume caused by bulky substituents and rigid backbone chains.
