polyVinyl Chloride – Plasticizer

Gidanian and Howard ¹ calculated the Hildebrand parameters of potential plasticizers for poly(vinyl chloride), particularly polymers from brassylic acid (tridecanoic acid) from the seed oil of Crambe abyssinica, by the methods of Small ² and Hoy. ³ The mean values are indicated in Table 1.
