Title:
METHOD FOR PRODUCING NORBORNENE POLYMER HAVING FLUOROSULFONYL GROUP, POLYMER HAVING SULFONIC ACID GROUP AND ELECTROLYTE MEMBRANE FOR FUEL CELL BY USING THE POLYMER
Document Type and Number:
Japanese Patent JP2008088247
Kind Code:
A
Abstract:
To provide a method for producing a norbornene polymer having a fluorosulfonyl group, and an electrolyte membrane for a fuel cell by using the polymer.
This method for obtaining a polymer containing a unit expressed by formula (a) is provided by polymerizing a compound expressed by formula (A) by using an organometallic complex catalyst. In the formula, X is methylene, methylmethylene, dimethylmethylene, O or S; QF is a polyfluoro divalent organic group; R is H, F or a polyfluoro monovalent organic group; and (k) is 0, 1 or 2.
