摘要： THE PRESENT IVENTION RELATES TO THERMOPLASTIC MOULDING COMPOSITIONS, CONSISTING OF TWO COMPONENTS IN A DETERMINED MIXING RATIO, ONE COMPONENT BEING POLYETHYLENE HAVING A MELT INDEX I2 (AT 190*C.) WITHIN THE RANGE OF FROM 0.4 TO 80 AND THE OTHER COMPONENT BEING A SEQUENCED COPOLYMER OF PROPYLENE AND ETHYLENE HAVING A MELT INDEX I10 (AT 190*C.) WITHIN THE RANGE OF FROM 0.5 TO 60. FURTHERMORE, THE PRESENT INVENTION PROVIDES A PROCESS FOR THE MANUFACTURE OF THESE MOULDING COMPOSITIONS. THE MIXTURES IN ACCORDANCE WITH THE INVENTION CAN BE PROCESSED TO SHAPED ARTICLES WHICH ARE DISTINGUISHED BY AN IMPROVED IMPACT STRENGTH AT LOW TEMPERATURES AND AN IMPROVE TRANSPARENCY, WHILE HAVING SUBSTANTIALLY THE SAME HARDNESS.

摘要： THERMOPLASTIC MOLDING COMPOSITIONS ON THE BASIS OF POLYOXYMETHYLENES ARE PROVIDED WHICH, BESIDES THE POLYOXYMETHYLENES, MAY CONTAIN POLYMERS OF VARYING COMPOSITION WITH A DEFINTE SIZE OF THE PARTICLES AS DISPERSED PHASE AND WHICH ARE NUCLEATED WITH SUCH AN AMOUNT OF INORGANIC NUCLEATING AGENT THAT THE SIZE OF THE POLYOXYMETHYLENE SPHERULITES FORMED UNDER DEFINITE CONDITIONS IS WITHIN A LIMITED RANGE. THE MOULDING COMPOSITIONS ARE SUITABLE FOR THE MANUFACTURE OF SHAPED ARTICLES OF ANY KIND AND HAVE IMPROVED MECHANICAL PROPERTIES.
