POLYMER COMPOSITIONS CONTAINING MAGNETICALLY SUSCEPTIBLE FILLERS |
摘要 |
The invention provides a method of influencing the orientation of the polymer molecules in a melt of molecularly orientable polymer by subjecting a composition containing the polymer and a megnetically susceptible filler to a magnetic field of at least 0.005 Tesla prior to or during the formation of a shaped article from the melt. Compositions for use in the invention comprise a thermoplastic polymer and at least 0.05% by weight of a magnetically susceptible filler, particularly a ferrite. The invention is most easily applied to thermotropic polymer compositions. |
