TRANSPARENT PARAMAGNETIC POLYMER |
摘要 |
This invention provides a transparent, paramagnetic polymer composition in which a polymer is complexed with sufficient rare earth ions, particularly ions selected from ions in the group of elements 64 - 69, to provide a polymer with a magnetic mass susceptibility greater than 20 x 10-6 emu/g measured at 298 DEG K. This invention provides optically responsive devices that employ these transparent, paramagnetic polymers as an element that is responsive to a magnetic field and a means for providing magnetic field. This invention provides transparent labels or markings employing these transparent, paramagnetic polymers. |
