PROCESS FOR THE PREPARATION OF A MELAMINE BASED FLAME RETARDANT AND POLYMER COMPOSITION

摘要

THE INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF A MELAMINE BASED FLAME RETARDANT BY A REACTION OF A MELAMINE COMPRISING COMPOUND AND A POLYOL IN A MOLAR RATIO BETWEEN 1.0:1 AND 4.0:1, WHEREBY THE REACTION IS PERFORMED IN AN EXTRUDER EQUIPPED WITH A DEGASSING MEANS, AT A TEMPERATURE BETWEEN 200 AND 300C. FURTHERMORE THE INVENTION RELATES TO A MELAMINE BASED FLAME RETARDANT OBTAINABLE BY SAID PROCESS AND A POLYMER COMPOSITION COMPRISING SAID MELAMINE BASED FLAME RETARDANT.
