Deproteinized natural rubber (DPNR) was prepared by incubation of the latex with 0.1 wt.% urea and 1 wt.% SDS at room temperature for 60 min followed by centrifugation at 10000 rpm for 30 min.
The working time of the graft copolymer was found to be longer and higher than that of the deproteinized natural rubber. It was proved by the master curves.
The deproteinized natural rubber (PDNR) was successfully prepared in the latex stage for both preservative systems by using EDTA-4Na in the presence of surfactant.
In the present work, an attempt to prepare nano-matrix-dispersed natural rubber from deproteinized natural rubber (DPNR) is performed with styrene or acrylonitrile as a monomer.
Graft-copolymerization of deproteinized natural rubber was carried out with tert-butyl hydroperoxide/tetraethylenepentamine as an initiator.
DP-Poly is a controlled viscosity, highly purified deproteinized natural rubber from which most of the proteins and ash have been removed.
The latter is the development of a new method to produce deproteinized natural rubber latex free from protein allergy.
The most recent commercially available grades are deproteinized natural rubber (DPNR), NR without foul smell (SUMAR) and epoxidized natural rubber (ENR), while the most established grades are methacrylate-grafted natural rubber (MG) and superior processing natural rubber (SP).
Deproteinized natural rubber has low protein and ash content.
signed a technology transfer agreement involving a process for the production of deproteinized natural rubber, produced by removing the proteins using an enzyme proteinase.
