Abstract

TO PROVIDE AN ECONOMICAL PROCESS FOR PRODUCING AN OXYMETHYLENE COPOLYMER EXCELLENT IN THERMAL STABILITY, A CRUDE OXYMETHYLENE COPOLYMER DISCHARGED FROM A POLYMERIZER IS PULVERIZED INTO A POWDER HAVING A SPECIFIED PARTICLE DIAMETER DISTRIBUTION AND SIMULTANEOUSLY THE POLYMERIZATION CATALYST IS DEACTIVATED AND THEN THE PULVERIZED OXYMETHYLENE COPOLYMER IS MELT-KNEADED TOGETHER WITH A STABILIZER TO OBTAIN A STABILIZED OXYMETHYLENE COPOLYMER SUBSTANTIALLY WITHOUT ANY TREATMENT FOR STABILIZING THE ENDS BY REMOVING THE UNSTABLE END PARTS BY DECOMPOSITION.
