Title:
PLASTIC COMPOSITION AND METHOD OF MAKING SAME
Document Type and Number:
Japanese Patent JPS5363455
Kind Code:
A
Abstract:
A plastic composition prepared by the reaction of a non-ionic water soluble acrylic polyelectrolyte and a cationic water soluble acrylic polyelectrolyte with propylene glycol and incorporating or conducting the reaction in the presence of polyvinyl pyrrolidone with or without water. In one embodiment a plastic composition adapted for use in contact with the skin, especially in the form of a pad, seal or bandage is prepared by reacting a mixture of: (1) acrylamide-beta methacrylyloxyethyl trimethyl ammonium sulfate copolymer; (2) polyacrylamide; (3) propylene glycol; and (4) polyvinyl pyrrolidone. The plastic composition can contain glycerin in varying amounts to enhance the "feel" and flexibility of the final product. Water can be incorporated with the polyvinyl pyrrolidone to reduce the gel time and facilitate the molding process. Useful embodiments of the composition having the proper gel structure and adhesiveness for use as molded seals or pads in ostomy appliances and skin-covering pads incorporated in a bandage are disclosed.
