Title:
METHOD OF MODIFYING POLYMERIC MATERIAL AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2001/048065
Kind Code:
A1
Abstract:
A method of modifying a polymeric material which comprises the steps of activation and treatment with a hydrophilic polymer, or comprises the steps of activation, treatment with a hydrophilic polymer, and monomer grafting in this order, or comprises the step of treatment with a solvent, followed by these steps. Thus, the polymeric material, e. g. , a polyolefin, is improved in hydrophilicity, adhesion, etc. without lowering the practical strength thereof. The polymeric material thus improved in adhesion and other properties can be used in many applications where water absorption and adhesion are required, such as an absorption material, e. g. , a wiping/cleansing material, a water retention material, a material for microorganism culture media, a separator for cells, a synthetic paper, a filter medium, a medical/sanitary/cosmetic supply, a textile product for clothing, and reinforcing fibers for composite materials.
