Abstract
PURPOSE: To prepare a polyoxymethylene giving an increased polymerization degree and improved thermal stability without additional stabilization treatment, by polymerizing formaldehyde in the presence of a specific catalyst supported on a carrier.
CONSTITUTION: A polyoxymethylene is prepared by polymerizing formaldehyde in the presence of a catalyst prepared by supporting an organoaluminum compound of the formula (R and R' are alkyl; n is 1W2), e.g. monoethoxydiethylaluminum or monoisobutoxydiisobutylaluminum, on a carrier, preferably, e.g. alkylenebisstearylamide, polyoxymethylene, etc
