Abstract
Abstract A surgical immobilizing bandage and the like which are quite excellent in various properties of moldability, durability, lightness in weight, water resistance, X-ray transmittance and so forth. The surgical immobilizing bandage of the invention is composed of the main constituent of an aliphatic polyester polymer or a mixture of aliphatic polyester polymers which are synthesized from aliphatic diols and saturated dicarboxylic acids. Further, the above bandage is prepared by impregnating an elastic fabric with a composition containing the above aliphatic polyester polymers, coloring agents and fillers.
