Microbiological deterioration of vulcanized rubber.
Data are presented which show that the constitution of the recovery medium exerts an appreciable effect on the apparent thermal resistance of spores of Putrefactive Anaerobe 3679. The routine use of a simple yeast extract-starch medium (YES) as a recovery medium in thermal resistance studies on this organism is recommended. In addition to giving thermal resistance values comparable to those obt...
متن کاملVulcanized rubber foot for lower limb amputees.
A prosthetic workshop was started some years ago at the S.M.S. Medical College Hospital , Jaipur , t o meet the growing demands of the local populat ion. Unlike the premier limb-fitting centres in India which still cater for the more affluent sections of society, it was decided that this centre would also look after the p o o r rural amputees . I t soon became apparent that a disturbing number ...
متن کاملThe Far-Infrared Spectrum of Deuterium Iodide.
We recently described an investigation of the far-infrared (FIR) spectrum of hydrogen iodide, HI, which resulted in an accurate set of rotational and I electric quadrupole parameters for the molecule in its XS (v 5 0) state (1). In this Note, we report an extension of this work to the deuterated form of the molecule, DI. The spectrum of deuterium iodide was recorded using the third-order tunabl...
متن کاملThe Cyclization of Natural Rubber
The effects of solvent, temperature, time, weight percent of catalyst on the rate and mechanism of cyclization of natural rubber (NR) was studied in toluene and xylene solutions having tin tetra chloride catalyst (SnCl4). Iodometric titration show, with 8% SnCl4 (based on polymer weight) cyclization occurs, leaving 27.4% of the total unsaturation. Infrared spectra of c...
متن کاملDegradation of Non-vulcanized Natural Rubber – Renewable Resource for Fine Chemicals Used in Polymer Synthesis
In the current scenario, there is growing interest in the products of degradation of rubber (natural and synthetic) for specific applications in different industry sectors, whose benefits in replacing conventionally used products are mainly related to sustainability. Since the degradation products of rubber can be used in different areas, several research groups may have the interest aroused by...
