Abstract
Rubber and gutta are both polymers of isoprene and have the empirical formula (C5H8)n. There is one double bond for each unit. The rubber hydrocarbon possesses the cis configuration and gutta hydrocarbon the trans configuration (Meyer, 1950, p. 186; Davis and Blake, 1937, p. 119; Saunders and Smith, 1949). Balata or balata gutta has been shown to possess the trans configuration also (Hendricks, Wildman and Jones, 1947) and future references to gutta in this chapter will include balata. Both hydrocarbons react with halogens form compounds which in many respects are indistinguishalbe from each other. As is true of rubber, gutta is readily oxidized and this oxidation occurs rapidly in solution if the solvent readily absorbs oxygen. In contrast to rubber, gutta is very resistent to ozone (Davis and Blake, 1937). Violet and ultra-violet light catalyze the oxidation of both hydrocarbons.
