Chemical Properties
Pergut S 20 is typically prepared by treating a solution of masticated natural rubber in chloroform or carbon tetrachloride with chlorine at 80-100°C until sampling indicates the product has a chlorine content of about 65%.
During this time, hydrogen chloride is evolved.
After the passage of chlorine has been stopped, the solution is refluxed until the evolution of hydrogen chloride ceases; this results in a product of good stability.
Pergut S 20 is then isolated by precipitation with methanol.
