摘要：Polymeric compositions characterized by containing polymeric acetals and zin c- containing inorganic fillers exhibiting improved resistance to the formation and adhesion of mineral deposits when used in applications wherein the composition is exposed to water containing dissolved minerals for extended periods of time. The composition may be prepared into shaped articles which are useful as mineral resistant, plumbing fixtures.
