Abstract
Incorporation into polyacetal of 0.01-15 weight percent of certain epoxy-containing polymer compounds, oxazolyl-containing monomer and polymer compounds, and/or styrene acrylonitrile graft polymer compounds yields polyacetal compositions having excellent tensile strength after long-term aging and also after long-term aging in grease. The compositions are useful in automotive and electrical/electronic applications.
