Abstract
In July, 1963, a working party of I.U.P.A.C. was set up to consider collaborative investigations in the general area indicated by the main title of this paper, and joint studies were started with three polymers: polystyrene, polyvinyl chloride, and polyethylene. This paper gives an account of the work done to date with polystyrene. The paper shows the detailed torsion pendulum results of six laboratories with the use of the same toughened polystyrene. The significance of frequency of vibration in raising the temperature of maximum damping of the rubbery component is clearly brought out and the degree of agreement shown between laboratories is good. A smaller number of collaborators made impact strength and torsion pendulum studies over a range of temperatures on polystyrene and another toughened polystyrene. The dependence of the brittle–tough transition temperature on estimated rate of elongation of the breaking filament is correlated with the dependence of the temperature of maximum damping of the rubbery component on frequency.Keywords
