Reaction Steps
A mixture (100 kg) of styrene and 2-vinylpyridine (30:70 by weight) containing 1% of initiator (azobisisobutyronitrile) is added in the course of 1 hour at a temperature of 65° C. to water (250 liters) containing 0.5% of amphiphilic surfactant (Rhodoviol 25/140). The polymerization is continued for 22 hours.
