Formation of Solid Free Radicals by Mechanical Action

Abstract

THERE is a marked reduction of the molecular weight of nitrocellulose on pulping, for the length of fibres is considerably reduced in the process1,2. Staudinger et al.3 have found a similar effect when polystyrene, cellulose and nitrocellulose are ground in a colloid ball-mill, and have also found that nitrocellulose is partially denitrated when grinding is prolonged. These observations indicate that purely mechanical cutting or breaking action can cleave covalerit bonds.
