natural rubber-SO_2 adductchemical structureNatural rubber (NR, cis-1,4-polyisoprene) was reacted in solution with SO 2 at room temperature in different solvents (tetrahydrofuran, CHCl 3, CH 2Cl 2 and tetralin). The reaction product consisted of an adduct between NR and SO 2. The ...
The accelerated thenno-oxidative aging of acrylonitrile butadiene rubber (NBR) was studied at elevated temperatures. The chemical structure characterized by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and pyrolysis gas chromatography mass spectroscopy (PGC-MS) showed the ...
HE Rubber Technology Conference, held in London during June 23-25 under the auspices of the Institution of the Rubber Industry, provided the first opportunity since the War for scientific workers and technologists in this field from many countries to meet for a general discussion of their problems...

In a high-speed slurry erosion test, wear was higher in the harder polymers but in a Dry Sand Rubber Wheel test, the softer polymers underwent greater wear. This change in rankings of the polymers was associated with a change in the wear mechanism from cutting and gouging in the slurry ...
