PURPOSE:To obtain a gel film excellent in strengths, stretchability, adhesion to the skin, water absorptivity and transparency and being useful as a wound- covering material by subjecting a polymer base to specified irradiation and grafting acrylic acid onto the base. CONSTITUTION:A polymer base (e.g. PE film) is irradiated with a radiation (e.g. accelerated electron beams) at a dose of 32 Mrad or above, and acrylic acid is grafted onto the base. |
