Natural cis-1 ,4-po1yisoprene occurs in over 2000 species of higher plants, the most well known of which is natural rubber from Hevea brasiliensis. Other plants, such as guayule (Parthenium argentatum), Russian dandelion (Taraxacum kok-saghyz), goldenrod (Solidago altissima), Jelutong (Dyera retusa), and fungal genera such as Lactarius volemus have ...

The Sulfonation of Natural Rubber
Rubber Chemistry and Technology, 1951Abstract Like many olefins, natural rubber is capable of reacting with sulfur dioxide, with formation of a sulfone. The reaction is a chain reaction which is started by certain catalysts. The structure of the rubber sulfone is: (see PDF for diagram) and the theoretical proportion of sulfur is 24.2 per cent.
