The temperature sensitivity of the system plasticizer‐polymer

Generally, in this paper, there are reviewed some of the factors influencing the properties of plastics, and additional evidence is provided through data on the rebound resilience; temperature relationships, for the current ideas on the plasticizer‐polymer interaction. Probably through the inferiority of mechanical tests compared with those of an electrical nature (Wurstlin, loc. cit.), the data are not so precise as to be quantitative but at least are of such a nature as to give further suport to the general theory of plasticizer viscosity and especially the relationship between the temperature dependence of plasticizer viscosity and that of plasticized compounds.
