<p><P>PROBLEM TO BE SOLVED: To provide a crosslinked polymer having proper viscoelasticities in molten state and in solid state respectively and useful as a material of a sheet for radiation therapy, a sheet for plaster cast, a patterning sheet for wig, tooth or the like. <P>SOLUTION: The crosslinked polymer is obtained by irradiating a polytransisoprene resin or an ethylenic copolymer resin each having a melting point of 40-80°C with active energy rays to cause crosslinking. The medical sheet comprises the crosslinked polymer. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
