Procedure

Swell 2.8 kg of styrene copolymer with 40 mol. percent of divinylbenzene, obtained in the presence of 100 percent by weight of isooctane, in 9 liters of dichloroethane, add a mixture of 2.0 kg of KNO3 and 5 liters of concentrated sulphuric acid, and keep for six hours at a temperature of -5° to 0° C. Proceed as in Example 1. The obtained textured nitro polymer contains 5.4 percent by weight of nitrogen.
