| titleOfInvention | A kind of organic concerted catalysis lactone ring opening polymerization without metal catalyst system |
| abstract | The invention discloses a kind of organic concerted catalysis lactone ring opening polymerizations without metal catalyst system, which belongs to high molecular synthetic material field, the controllable active ring-opening polymerisation applied to efficient catalyzing lactone.Preparation method of the present invention is under inert gas protection, using lactone as monomer, in organic solvent, by alkene outside N- heterocycle and thiocarbamide concerted catalysis or by alkene outside N- heterocycle and urea concerted catalysis, and to cause lactone by alcohols and carry out ring-opening polymerization.In organic solvent, without metal residual in obtained aliphatic hydrocarbon polyester polymer, reaction condition is mild, rapid reaction, and polymerization process is simple to operation for this synthetic methodï¼›High conversion can be obtained, and the polyester material of narrow molecular weight distribution can be obtained under the action of few catalytic amount. |
