POLYOXYMETHYLENE COMPOSITIONS WITH BRANCHED POLYMERS

摘要

Polyoxymethylene compositions with polyoxymethylene polymers polymer/polyol additives having a core-link-arm structure. Upon molding, these compositions exhibit stable melt viscosity and simultaneous improvement in notched Izod impact strength and/or decreased relative apparent capillary melt viscosity, and/or increased elongation at break, relative to polyoxymethylene compositions lacking such core-link-arm structure additives.
