The formation of free radicals in polystyrene by ball milling

BY BALL MILLING. Though the mechanical breakdown of polymers is not a new process, until recently the actual mechanism of the degradation had never been determined but had been assumed to be thermally induced (1). In 1952 it was shown by Watson and co-workers (2) that, for rubber, the degradative process was.

In some cases more “soft milling conditions” with low ball-to-powder ratios and small ball sizes which intense the frictional action are helpful to support amorphization and metastable phase formation in alloying. Small balls are also useful if no high intensity but more an efficient mixing and/or a high number.

Ball Mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral.
