Abstract
Abstract Several comparative investigations of various types of raw rubber have been published, but most of these refer to products of different origin, hence it is not known to what extent the results depended on natural variations in the rubber. Moreover, the investigators, who prepared their own material, worked either with old latex in Europe, in the United States or in the tropics, where the work was confined to only a few types of rubber. The present investigation was conducted with the following objects in view : (1) A comparison of various types of commercial rubber, i.e., smoked sheet, crepe and whole-latex rubber. (2) A comparison of these rubbers with those obtained from different types of latex (or cream latex). (3) The influence of storage of latex (cream latex) on the properties of the rubber. (4) The influence of storage on various types of, rubber. (5) A comparison of the accelerated aging tests of Geer and Evans and of Bierer and Davis.
