Thermal oxidation studies on methyl grafted natural rubber
Thermal oxidation studies on methyl grafted natural rubber polymer electrolytes with paraphenylene diamine additive Abstract: This work is concerned in improving the resistance against thermal oxidation of polymer electrolyte based on 30 % methyl grafted natural rubber (MG30) by adding antioxidant N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) with different weight percent between 0.5 and 8 wt.%.

Enhancement the Thermal Stability and the Mechanical
The prepared natural rubber-graft-o-Aminophenol, NR-graft-o-AP, was analysed by using Infrared and 1H-NMR Spectroscopy techniques. The thermal stability, mechanical properties, and ultrasonic attenuation coefficient were evaluated for NBR vulcanizates containing the commercial antioxidant, N-phenyl-?-naphthylamine (PBN), the prepared grafted antioxidant, NR-graft-o-AP, and the control vulcanizate.

Preparation, Adhesive Performance and Stability of Natural
In order to study the potential of increasing the weather stability of natural rubber latex for use as a water-based contact adhesive, the natural rubber latex was modified by graft copolymerization with n-butyl acrylate (BA) and methyl methacrylate (MMA). The grafting reaction was carried out using emulsion polymerization at 60°C.

Aging and Oxidation of Elastomers | Rubber Chemistry
Natural rubber and synthetic elastomers deteriorate on aging as a result of the contribution of a number of factors. It has been generally recognized for many years that the changes in properties on aging are due primarily to the deteriorating effects of one or more of the following factors: heat, light, oxygen, and ozone.

Thermal and Oxidative Degradation of Polymers
Thermal and Oxidative Degradation of Polymers In recent decades synthetic polymeric materials, be-cause of their unique physical properties, have rapidly replaced more traditional materials such as steel and nonferrous metals, as well as natural polymeric materi-als such as wood, cotton, and natural rubber. However,

Degradation of Rubber
Thermal-Oxidative Degradation of Rubber Most elastomers will undergo significant changes over time when exposed to heat, light, or oxygen (ozone). These changes can have a dramatic effect on the service life and properties of the elastomers and can only be prevented or slowed down by the addition of UV stabilizers, antiozonates, and antioxidants.
