Abstract
Compositions comprising polyoxymethylene polymers and at least one organopolysiloxane polymer. Adding organopolysiloxane polymers to polyoxymethylene polymers provides compositions that exhibit at least a 50 percent reduction in melt viscosity compared to the melt viscosity of an identical, melted composition lacking the organopolysiloxane polymer, and promote easier molding of the compositions into complex article shapes.
