Abstract

Solid thermoplastic terpolymer of trioxane is prepared by reacting trioxane in the presence of a prepolymer having recurring units consisting essentially of about 87-99 percent by weight of units derived from at least one cyclic formal and about 13-1 percent by weight of units derived from diglycerin diformal.
