Method for modifying polyfumaric acid diester. |
摘要 |
According to the invention, a method for modifying a polyfumaric acid diester is provided. The method comprises subjecting the polyfumaric acid diester to thermal treatment to thereby obtain a polyfumarate having carboxyl groups. The polyfumaric acid diester is obtained by polymerizing a fumaric acid diester represented by the following general formula of: <IMAGE> wherein R represents an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 3 to 12 carbon atoms or an organic residue having at least one aromatic ring. |
