POLYOXYMETHYLENE POLYMER WITH LONG CHAIN ALKYLENE GLYCOL END GROUPS

摘要

A polyoxymethylene polymer is disclosed that contains long-chain alkylene glycol end groups. The polyoxymethylene polymer may be formed by using a Bis- oligo-alkylene glycol-formal as a chain transfer agent during production of the polymer. The end groups on the polyoxymethylene polymer may comprise ethylene oxide end groups and/or propylene oxide end groups. The resulting polymer has excellent flow characteristics and may be used as a flow additive for other thermoplastic polymers. Alternatively, the polymer may be used to form various molded articles with excellent tribological properties.
