Title:
低放散性着色ポリオキシメチレン成形材料
Document Type and Number:
Japanese Patent JP5379338
Kind Code:
B2
Abstract:
Colored molding compositions made from polyacetal copolymer, where the polyacetal copolymer essentially consists of oxymethylene units and oxyethylene units, and a strong protonic acid was used as initiator during preparation of the polyacetal copolymer, have lower formaldehyde emission than that from a comparable molding composition for which the polyacetal copolymer was prepared using a Lewis acid as initiator. The formaldehyde emission is generally less than 20 mg/kg, preferably less than 10 mg/kg.
