Abstract

"Process for manufacturing a copolymer" containing oxymethylene units, characterized in that a formaldehyde cyclic oligomer is subjected to polymerization conditions together with a cyclic ether of the structure ** (See formula) ** wherein the divalent radical R is derived, by separation of the two hydroxyl groups, from an aliphatic diol containing ethylenic unsaturation in the chain between the hydroxyl groups, and R1 and R2 can be hydrogen atoms or monovalent hydrocarbon radicals, the same or different, in the presence of an electrophilic catalyst and, only, a very small amount of water.
