Tensile strength–modulus relationships established for postvulcanised latex films have been found to show characteristics of both prevulcanised latex and dry rubber curves. The curves depend upon the accelerator system used, as with dry rubber. They passed through their maxima after which tensile strength fell, with the down-turn less pronounced than for prevulcanised latex but greater than for dry rubber. The results suggest that postvulcanised latex films remain particulate rather than homogeneous. Processes known to affect prevulcanised latex films were applied to postvulcanised latex films. These included stirring and maturation of latex, different conditions for drying films and leaching with water and solvents, but only stirring had a significant effect. Stirring was essential to produce homogeneous latices for films with consistent chemical compositions and physical properties. [Continues.]
