Abstract

THE PRESENT INVENTION RELATES TO A METHOD FOR PRODUCING A POLYACETAL COPOLYMER BY POLYMERIZING A TRIOXANE, USED AS A MAIN MONOMER, WITH A CYCLIC ETHER AND/OR A CYCLIC FORMAL HAVING AT LEAST A CARBON-CARBON BOND, USED AS A COMONOMER, WHICH COMPRISES COPOLYMERIZING BY THE USED OF A SPECIFIED HETERO-POLYACID AS A POLYMERIZATION CATALYST, ADDING A SOLID BASIC COMPOUND AS A DEACTIVATOR OF THE CATALYST TO THE REACTION PRODUCT OBTAINED, AND THEN, CONDUCTING A MELT-KNEADING TREATMENT OF THE ADDITION MIXTURE TO DEACTIVATE THE CATALYST, AND ACCORDING TO THE PRESENT INVENTION, A POLYACETAL COPOLYMER IS PRODUCED HAVING AN EXTREMELY LITTLE AMOUNT OF AN UNSTABLE TERMINAL PART, BEING VERY STABLE TO HEAT, AND BEING LEAST IN A RELEASING AMOUNT OF ALDEHYDE THEREFROM , USING A SIMPLE PROCESS IN WHICH DEACTIVATION OF A CATALYST CAN BRIEFLY BE CONDUCTED, A WASHING OPERATION IS UNNECESSARY AND A HIGH POLYMERIZATION YIELD CAN BE OBTAINED.
