Chemical Modification of Natural Rubber as a Route to Renewable Resource Elastomers

  • Chapter
Book cover Renewable-Resource Materials

Abstract

Natural rubber (NR) is commonly obtained from the latex of the Hevea brasiliensis tree, which is indigenous to South America. The latex is contained within a system of anastomosing articulated vessels which occur in the region of the phloem as sheaths concentric with the outer bark. There are limited anastomoses between each ring of vessels forming a continuous network and thus allowing the withdrawal of latex to be made by repetitive tapping without serious damage to the tree. NR can also be obtained from the Guayle plant (Parthenium argentatum) but in this case the latex is present in ordinary parenchyma cells and the whole plant has to be sacrificed to obtain the rubber. A Hevea tree has a useful productive life of between fifteen and twenty years and is by far the most efficient source of natural rubber.
