Abstract
1536964 Oxymethylene copolymer granules HOECHST AG 26 Feb 1976 [28 Feb 1975] 07628/76 Heading C3L Oxymethylene copolymers containing 0À1- 20% by weight of C 2 -C 8 oxyalkylene units are prepared in granular form by adding a solution or dispersion of the copolymer in methanol/ water having a temperature 5-65‹ C. above the sintering temperature of the copolymer to a turbulent methanol/water mixture having a temperature 1-10‹ C. below said sintering temperature, thereby precipitating granular copolymer; and separating and drying the granular product.
