摘要： A composition is provided comprising a major amount of normally crystalline acetal polymer and lower amounts than said crystalline acetal polymer of a thermoplastic polyurethane and a normally non-crystalline acetal copolymer of monomers comprising about 15 to 45 mol % of trioxane and about 55 to 85 mol % of 1,3-dioxolane based on the total of trioxane and 1,3-dioxolane. The composition may be molded into articles having high impact strength.

摘要： Ultraviolet curable terpolymers of trioxane, from at least 65 weight percent to about 75 weight percent of 1,3-dioxolane and from about 2 weight percent to about 20 weight percent of a monoethylenically unsaturated aliphatic diol formal having at least 4 carbon atoms in its main chain, e.g., 4,7-dehydro- 1,3-dioxepin, which are non-crystalline at room temperature or above are disclosed. These terpolymers, when admixed with a multifunctional crosslinking monomer, e.g., a multifunctional acrylate such as 1,6-hexanediol diacrylate, and a photosensitizer, e.g., a benzoin compound such as benzoin isobutyl ether, can be cured to an insoluble, non-tacky, rubbery state using UV radiation. The thus-cured polymeric materials form useful crosslinked films, and when cryogenically ground to a suitable small particle size can be blended with conventionally prepared crystalline oxymethylene homo-, co- and terpolymers to improve the latters' impact properties.

摘要： 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.
