Method for preparing polymer |
摘要 |
<p>The present invention provides a method of preparing a polymer, which comprises subjecting a monomer containing at least a polar unsaturated compound to anionic polymerization in the presence of a phosphazenium compound represented by the formula (1): <CHEM> (wherein Z<-> is an anion of an active hydrogen compound in the form where a proton is eliminated from the active hydrogen compound and transferred to the anion; a, b, c and d each represents 1 or 0, but all of them are not simultaneously 0; and R may the same or different and each represents a hydrocarbon group having 1 to 10 carbon atoms, and two R(s) on the same nitrogen atom are optionally combined each other to form a cyclic structure), or in the presence of the phosphazenium compound and the active hydrogen compound. The resulting polymer is characterized by narrow molecular weight distribution.</p> |
