Introduction of a Luminophore into Generic Polymers via

14-05-2021Herein, we report a novel strategy for introducing a luminophore into generic polymers facilitated by mechanical stimulation. In this study, polymeric mechanoradicals were formed in situ under ball-milling conditions to undergo radical–radical coupling with a prefluorescent nitroxide-based reagent in order to incorporate a luminophore into the polymer main chains via a covalent bond.

Ball Mill Bond Efficiency

Ball Mill Bond Efficiency. The ability to simulate the bond work index test also allows examination of truncated ball mill feed size distributions on the work index.For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill see figure 3.10, a question arises as to whether this practice will alter the ball mill work index
