Abstract
Addition of potassium persulphate to a latex leads to cross-linking with typical diene polymers but has little effect on polystyrene. The rate of cross-linking is directly proportional to the persulphate concentration. The activation energy is 26,900 cal. The rate depends on latex particle size and is affected by the presence of other reagents. The course of gelation supports the predictions of the statistical theory of random cross-linking.Keywords
