| Abstract: | The effects of the concentration of internal lubricants on the deformation and fracture of commercial polystyrenes produced by bulk and suspension polymerization routes are described. The addition of internal lubricant in the range 0 to 6% was shown to cause a decrease in the extent of craze-yielding and in the incidence of secondary fracture features, and over-all the changes in behaviour were similar to those observed when the test temperature is increased. |
