The Instability of Hevea Latex
Rubber Chemistry and Technology, 1941Abstract In a study made on plantations in Malaya, it was found that the cause of instability is not the same for both fresh and preserved latex. The autocoagulation of fresh latex, as it will be shown, is not caused by the acid formed by bacterial action on the serum components (autoacidification). Coagulation takes place, in fact, when

The Coagulation of Hevea Latex
Rubber Chemistry and Technology, 1930Abstract In checking up as to which substances are present in latex, we find the following: protein, which can act as a protective colloid, lipoids (sterols, lecithin which can protect the sterol, esters of sterols), and further the contents of the globules, which is probably viscous.

The genus Hevea is a member of the Euphorbiaceae and is endemic to the Amazon basin and its neighbouring parts including Matto Grosso, Upper Orinoco and the Guianas. The taxonomy of the genus has been intensively studied (29). Nine species are now recognized in the genus and of these only H. brasiliensis is important economically.

Chain Scission in the Oxidation of Hevea. II
Journal of the American Chemical Society, 1955Abstract Oxidation of natural rubber in latex yields two molecules of carbon dioxide, one of formic acid and one of acetic acid for each rupture of the hydrocarbon chain. The yields of these products can be interpreted readily by reference to the structure of the primary oxidation products of 1,5-diolefins established by Bolland and ...

Kinetics of Cyclization of Hevea Latex
Industrial & Engineering Chemistry, 1951Abstract Kinetic measurements on rubber cyclization now are possible by a latex technique; these were undertaken to elucidate the mechanism of the reaction. According to a patented process, dispersions of Hevea latex particles in 70 to 80 per cent sulfuric acid are reproducibly isomerized to a high molecular weight cyclized rubber.

Statistical Kinetics of Hevea Rubber Cyclization
Rubber Chemistry and Technology, 1951Abstract Rubber cyclization provides a useful illustration of statistical effects intervening in the reactions of long-chain polymers. Analogously to the known cyclizations of simple diisoprenic terpenes, each individual cyclization act links two adjacent isoprene units in the rubber chain into a six-membered ring.
