摘　　要：A new fixed carder membrane material VSA-SA for CO2 separation was prepared through the chemical modification of PVSA. The selective permeation of CO2 through VSA-SA/PS composite membrane was performed with CO2/CH4 system. The VSA-SA/PS composite membranes possess better CO2 permselectivity than PVSA/PS composite membrane.
