THE CONSTITUTION OF RUBBER 



47 



Summary 



A survey of the facts of rubber chemistry is given and a criticism 

 of the interpretations of these facts by previous investigators presented. 



A new constitutional formula for rubber is advanced, which 

 seems more in harmony with these facts. 



Some new oxygen and iodine derivatives of rubber are described 

 which substantiate this constitution. 



Provisional formulae are presented for the constitutions of these 

 derivatives. 



This work is being continued in this laboratory.
