Abstract
Low Tg copolymers 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, are disclosed. These polymers, when blended with crystalline oxymethylene polymers, improve the latter's impact properties. They can also be used as adhesives for crystalline oxymethylene polymers.
