发明名称 Obtaining Melt Viscosity Stability of Polyoxymethylene Compositions
摘要 Processes for improving melt flow properties of molten compositions with polyoxymethylene polymers and polymer/polyol additives having a certain core-link-arm structure, which include: obtaining melt viscosity stability while improving notched Izod, decreasing relative apparent capillary melt viscosity, and increasing elongation at break relative to molten compositions of polyoxymethylene polymers without the polymer/polyol additives.
