Abstract
Formaldehyde and acetaldehyde are copolymerized in the presence of a solvent of the two monomers which is not a solvent for the polymers of the polymers or copolymers of the monomers, and of a polymerization catalyst other than naphthalene-sodium. The solvent may be anhydrous and polar-diethyl ether, ethylene glycol dimethyl ether and tetrahydrofuran are specified. The polymerization may take place at below ambient temperature and under vacuum or under an inert atmosphere. Specified catalysts are tertiary amines, e.g. tributyl amine. Specification 927,819 also is referred to.
