The title compound, [Sb(C5H10NS2)3], was synthesized from Sb2O3, diethylamine, carbon disulfide, hydrochloric acid and sodium hydroxide. The structure has been published previously but H atoms were not included in the model [Raston & White (1976 ▶). Chem. Soc. Dalton Trans. p. 791]. The current determination has significantly higher precision than the original work. The complex has three ligands. The Sb atom is coordinated by three bidentate diethyldithiocarbamate groups, two in an almost planar fashion and the third perpendicular to that plane with a dihedral angle of 86.429 (13)°. One ethyl group is disordered over two positions of equal occupancy.
PP/EPDM blends were prepared by dynamic vulcanization technology within a HAAKE torque rheometer. The effect of different plastic/rubber ratios of PP/EPDM blends on the curing behavior and crystallization kinetics were investigated. The obtained results showed that the plastic/rubber ratios played an important part in the solidification process as well as the crystallization kinetics. With increasing EPDM content, the cooling rate of PP/EPDM blends was significantly larger than that of neat PP. When PP content was 20 wt%, the crystallinity of PP was obviously larger than that of neat PP. Compared with neat PP, the crystallization temperature of the blends were remarkably shifted to the lower temperature. EPDM particles showed active effect on the nucleation process of PP during the cooling crystallization of the PP/EPDM blends.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
