<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a modified polyolefin-based resin by introducing a double bond in its main chain easily or substituting the part of its side chain without reducing its degree of polymerization widely. <P>SOLUTION: This method for producing the modified polyolefin-based resin is provided by performing the elimination reaction of a resin expressed by general formula (1) [wherein, l is an integer; and X is a halogen, hydroxy, carboxy, aryl, or a compound bonded with the main chain by an ether bond or bonded with the main chain by an ester bond] in a supercritical fluid or a semi-supercritical fluid to produce the modified polyolefin-based resin having a structure expressed by general formula (2) [wherein, (m), (n) are each an integer; and X is a halogen, hydroxy, carboxy, aryl, or a compound bonded with the main chain by an ether bond or bonded with the main chain by an ester bond]. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
