A new fixed carrier 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.
