The disclosure relates to transition metal compositions, methods of making the compositions, articles prepared from the compositions, and methods of making the articles. Provided is a transition metal master batch composition comprising: (a) a solid polymer carrier comprising a polyester polymer; and (b) a transition metal composition comprising cobalt, wherein the transition metal composition is dispersed in the solid polymer carrier; wherein the cobalt in the transition metal composition is present in an amount greater than about 30,000 ppm (by metal) based on the weight of the transition metal master batch composition. Also provided is a transition metal compact composition comprising, and a method of making, the transition metal master batch composition. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention. |
