Abstract
Oxymethylene polymer bonded articles, such as multilayer laminates, are disclosed. Such articles are prepared by bonding together at least two articles shaped or molded from crystalline oxymethylene homo-, co- and terpolymers using, as an adhesive, a low Tg copolymer of trioxane and 1,3-dioxolane which have a dioxolane content greater than 65 mol percent and less than about 75 mol percent and an IV of from about 1.0 to about 2.3, and which are non-crystalline at room temperature or above.
