Four multistranded copolymers were synthesized by two-step selective polymerization of monomers having an acetylene and two olefins. Their second main chains, which were formed at the postpolymn. between the olefin groups in the template acetylene polymers, are categorized into two types, i.e., helical conformations along with the conformations of their template helical polymers and nonhelical conformations parallel to the direction of the main chain of their precursor polymers. The numbers of the strands are two, four, and seven when supramol. strands by hydrogen bonds are included. Since the copolymers were all soluble, they could be fully characterized and fabricated to self-standing membranes. The conversions of the postpolymns. were high. The degree of the postpolymn. could be controlled by changing conditions. Oxygen permselectivies of these multistranded copolymers were better than the corresponding template polymers. The more the number of the strands was, the higher their oxygen permselectivity showed.
