Abstract

Abstract PURPOSE:To obtain a novel polymer of a specific intrinsic viscosity, with excellent selective permeability, suitable for gas separation membranes, composed of a specific allylsilane recurring unit. CONSTITUTION:(A) A monomer corresponding to a recurring unit of formulaI [R1-R3 are each alkyl, cyloallyl, or allyl with the total number of carbon atom (S) meeting the formula: 4<=S<=15]together with, if necessary, (B) a monomer corresponding to a second recurring unit of formula II is polymerized, in the presence of a catalyst, at 10-120 deg.C to obtain the objective polymer with a ratio of the recurring unit of the formulaIto that of the formula II being 100/0-10/90, having an intronsic viscosity determined in the form of a cyclohexene solution of 0.5g/100cc of 0.5-5.0 at 25 deg.C.
