| Summary, etc | The effect of water-soluble polymers (WSPs), such as polyvinyl alcohol (PVA) and polyvinyl pyrolidone (PVP), on radiation-vulcanised natural rubber latex (RVNRL) was investigated. Extractable protein measurements showed that mixing of WSP into RVNRL, followed by centrifugation, effectively reduced the extractable protein from RVNRL. However, extractable protein could be further effectively removed from RVNRL by adding low-molecular-weight PVA (LMW-PVA) and PVP followed by 20 min leaching in 1;ammonia solution, was sufficient to produce RVNRL free of soluble proteins. Based on these results a new process has been developed by the incorporation of LMW-WSP iinto RVNRL and centrifugation, followed by leaching. Tensile properties such as tensile and tear strength, were comparable to those of conventional RVNRL. Fourier Transform Infrared measurements showed that most of the WSP was removed from RVNRL during the centrifugation process. The viscosity of the RVNRL was not much affected by the addition of LMR-WSP. |
