Title:
METHOD FOR PRODUCING POLYACETAL POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/136005
Kind Code:
A1
Abstract:
This method for producing a polyacetal polymer includes: a step (A) for homopolymerizing trioxane; or a step (B) for copolymerizing a primary monomer, which is trioxane, and a comonomer, which is a compound copolymerizable with the trioxane. In said steps, a compound represented by general formula (1) is used as a polymerization catalyst. (In general formula (1), R represents an aliphatic hydrocarbon group or an aromatic hydrocarbon group that is optionally substituted; m and n each independently represent an integer between 0 and 10; and x represents an integer between 1 and 3.)
