        "The original of liquid natural rubber dated back to 1923 by mechano-chemical degradation of solid natural rubber8,18. It found application in the field of adhesives5. The study of photochemical depolymerization of rubber had been carried out by MRPRA, allowing short polyisoprenic chain with carboxylic ends. Ozonolysis was another reaction that caused degradation of the rubber chain. Institut de la Recherche Applique sur les Polymeres (IRAP) in France developed a method of preparation of LNR based on oxidative degradation reaction of natural rubber in the latex state at a moderate temperature by using phenylhydrazine and oxygen system. Pautrat et al. studied influence of different parameters of oxidative degradation of natural rubber. They found that the molecular weight of LNR obtained was effected by the following parameters: amount of phenylhydrazine, rate of air flow, reaction time, and temperature of the reaction."
