A process for the polymerization of formaldehyde, comprising contacting formaldehyde in a hydrocarbon solution with an aliphatic anhydride and a quaternary ammonium salt polymerization initiator of the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>R1R2R3R4N+X-<?in-line-formulae description="In-line Formulae" end="tail"?> where R1 is an aliphatic or olefinic hydrocarbon group containing about 18 to about 25 carbon atoms; R2, R3, and R4 are each methyl, ethyl, and/or propyl, such that the total number of carbon atoms in R2, R3, and R4 combined is between 3 and 7; and X- is an organic anion. |
