Production of polyoxymethylene and suitable catalysts |
| abstract |
A process is described for preparing polyoxymethylene by contacting a formaldehyde source with a catalyst of the formula I n n[ML 1 a L 2 b ] c m+ Z c·m/n n− (I) nwhere M is a metal of group VIII; n L 1 is a ligand having at least one π-electron pair; each L 2 is independently tetrahydrofuran or a ligand which is displaceable by tetrahydrofuran; Z is an anion; a is 1 or 2; b is an integer from 0 to 4; c is 1 or 2; and m and n are integers from 1 to 4. |
