Polymeric, elastomeric, or latex compositions including a water-based emulsion of a polyisoprene polymer; a first accelerator comprising at least one of a thiourea, a thiazo!e, or a dialkyl dithiocarbamate, or combinations thereof; a second accelerator comprising a thiuram or a xanthogen, or a combination thereof; at least one antioxidant; at feast one vulcanizing agent; and an activator; wherein a total amount of the first accelerator and the second accelerator ranges from 0.2 to 2.5 PHR of the polymeric, elastomeric, or latex composition and the polymeric, elastomeric, or latex composition is free of diphenyl guanidine or casein, are disclosed.
The syntheses of eleven sultam thioureas, including nine new compounds, are described. These compounds were synthesized from thioureas and include the first sultam thioureas in which the two thiourea nitrogen groups are not identical. In addition, the first X-ray crystal structures of sultam thioureas and the antiviral activity of these compounds against West Nile virus (WNV) are reported.
本文介绍了十一种舒坦硫脲的合成方法,其中包括九种新化合物。这些化合物是由硫脲类化合物合成的,其中包括首个两个硫脲氮基团不完全相同的舒坦硫脲类化合物。此外,还首次报道了苏丹硫脲类化合物的 X 射线晶体结构以及这些化合物对西尼罗河病毒(WNV)的抗病毒活性。
