Silicone rubber and natural rubber as biomaterials
Medical & Biological Engineering & Computing, 1980The roles of silicone rubber and natural rubber as biomaterials are contrasted, with silicone rubber being widely used and natural rubber having, as yet, found limited application. Relevant properties of both elastomers are described, applications are discussed and possible future developments are considered.

The cyclization of natural rubber
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1963Several methods of measuring the unsaturation remaining in natural rubber after cyclization have been compared. Approximate agreem ent was obtained with the reagents, perbenzoic acid, phenyl iododichloride and ozone; iodine chloride gave high values. Perbenzoicacid is considered the most satisfactory of these reagents. The unsaturation in some cyclized

Abstract When natural rubber is epoxidized under carefully controlled conditions, it can be converted to a totally new polymer with some properties more akin to speciality rubbers and some properties that appear to be advantageous for tire treads. Three levels of epoxidation have been extensively evaluated.

Infrared studies on natural rubber and aged natural rubber
Journal of Polymer Science, 1955AbstractIn the infrared absorption spectra of solutions of natural rubber in carbon tetrachloride, two new absorptions are observed, one at 6.52 μ and another at 8.2 μ. These bands disappear when films from the solution are examined. Possible origins of these bands are discussed and it is suggested that the absorption at 6.52 μ may be due to a ...

Natural and Synthetic Rubber. VII. Fractional Precipitation of Natural Rubber
Rubber Chemistry and Technology, 1931Abstract Temperature—concentration diagrams are given of the systems natural rubber—alcohol—benzene, pure rubber—alcohol—benzene and synthetic rubber—alcohol—benzene. A method based on these diagrams is given for the separation of nitrogen-free rubber hydrocarbon by fractional precipitation of natural rubber from a mixture of alcohol and

Epoxidized Natural Rubber/Chitosan Network Binder for Silicon Anode in Lithium-Ion Battery.
ACS Applied Materials and Interfaces, 2018Polymeric binder is extremely important for Si-based anode in lithium-ion batteries due to large volume variation during charging/discharging process. Here, natural rubber-incorporated chitosan networks were designed as a binder material to obtain both ...
