The printability of oxymethylene polymers such as by the heat transfer of sublimable dyes is improved by the addition of an amorphous or partially crystalline polymer to the oxymethylene polymer molding composition.

Printable polyacetal compositions

The invention relates to acetal polymer molding compositions having improved impact strength and containing lower amounts than the acetal polymer of a thermoplastic polyurethane, e.g. a polyether- or polyester- based polyurethane, and a multiphase composite interpolymer, e.g. comprising an elastomeric acrylic phase onto which is grafted a rigid thermoplastic polymeric phase. The composition is preferably blended at a shear rate of less than about 5000 sec.sup.-1.
