| Abstract: | Natural polymer chitosan supported yttrium complex has been synthesized for the first time.The ring opening polymetirption of epichlorohydrin catalyzed by the ternary system contajning this complex was studied in detail with emphasis on the polymerization regularity. The result show that the catalytic system is of high activity for preparing low ctystallinity, high molecular weight polyepichlorohydrin. |
