| titleOfInvention | Production of polyoxymethylene |
| abstract | PURPOSE: The polymerization of formaldehyde is conducted employing a catalyst of a specific complex from an aluminum compound and an amine supported on a specific amide compound to yield polyoxymethylene of high polymerization degree and high thermal stability. n CONSTITUTION: An aluminum compound of formula I (R, R 1 are alkyl; 1 is 1W3) such as diethylaluminum monoethoxide is mixed with an amine such as pyridine preferably in an amount of 0.5Wdouble the moles of the aluminum compound to form a complex. Then the resulting complex is supported on an amide of formula II (R 8 is 1W10C alkylene; R 9 is 1W25C alkyl) such as methylenebisstearoylamide in an amount of 10 -2 W10 -5 mol/g on the aluminum base. The polymerization of formaldehyde such as slurry polymerization is conducted using the resulting catalyst to produce the objective polyoxymethylene. n COPYRIGHT: (C)1979,JPO&Japio |
