Natural and Synthetic Rubber. VII. Fractional Precipitation of Natural Rubber

Rubber Chemistry and Technology, 1931
Abstract 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

Natural Rubber

2009
Natural rubber, India rubber and caoutchouc are all names for the solid elastic material isolated, one way or another, from the ‘milk’ or latex of Hevea brasiliensis, and various other tropical plants like Castilloa elastica.

Dual Cross-Linked Self-Healing and Recyclable Epoxidized Natural Rubber Based on Multiple Reversible Effects

ACS Sustainable Chemistry and Engineering, 2019
Generally, self-healing research based on commercial rubber is of great significance in sustainable development by extending the lifetime of materials. However, it is still a great challenge so far to prepare recyclable rubber that combine excellent self-

Enhancing the EMI shielding of natural rubber-based supercritical CO2 foams by exploiting their porous morphology and CNT segregated networks.

Nanoscale, 2019
Natural rubber/carbon nanotubes composite foams (F-NR/CNTs) with high electrical conductivity and excellent electromagnetic interference (EMI) performance were developed through a multi-step process including: (a) CNTs assembled on natural rubber latex ...

Epoxidized Natural Rubber/Chitosan Network Binder for Silicon Anode in Lithium-Ion Battery.

ACS Applied Materials and Interfaces, 2018
Polymeric 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 ...

Cryoground Rubber-Natural Rubber Blends

Rubber Chemistry and Technology, 1984
Abstract Addition of cryoground rubber (CGR) causes changes in curing characteristics (decrease in Mooney scorch time, optimum cure time, and reversion time) and shows a detrimental effect on most of the vulcanizate properties (tensile, resilience, flex, hysteresis, set, and abrasion). Tear strength, however, is not adversely affected by

Natural Polymer Eucommia Ulmoides Rubber: A Novel Material.

Journal of Agricultural and Food Chemistry, 2021
As the second natural rubber resource, Eucommia ulmoides rubber (EUR) from Eucommia ulmoides Oliver is mainly composed of trans-1,4-polyisoprene, which is the isomer of natural rubber cis-1,4-polyisoprene from Hevea brasiliensis.

Effect of carbon black loading on mechanical and rheological properties of natural rubber/styrene-butadiene rubber/nitrile butadiene rubber blends

Journal of Thermoplastic Composite Materials, 2019
This study investigated the effect of carbon black (CB) filler loading on mechanical and rheological properties of natural rubber (NR)/styrene-butadiene rubber (SBR)/nitrile butadiene rubber (NBR) ternary rubber nanocomposites.

Natural rubber latex allergy

Clinical and Experimental Dermatology, 1999
Rubber is an important industrial and consumer product encountered in many household items and medical devices. Whereas the chemical additives used in its manufacture are well recognized as a cause of delayed-type hypersensitivity (allergic contact dermatitis), it is only during the past decade that immediate-type allergy to natural rubber latex (NRL ...

NATURAL AND SYNTHETIC RUBBER. I. PRODUCTS OF THE DESTRUCTIVE DISTILLATION OF NATURAL RUBBER

Journal of the American Chemical Society, 1929
Abstract Two hundred pounds of pale crepe rubber have been destructively-distilled at atmospheric pressure. The distillate was fractionated and its components identified from C5 to C10, as shown in the table. Assuming that the Staudinger formula is correct, that the single bonds furthest from the double bonds are the weaker spots and ...
