The accelerators evaluated were TMTD (tetramethylthiuram disulfide), ZDMC (zinc dimethyldithiocarbamate), MBTS (2,2'-dibenzothiazole disulfide), TBBS (N-tertbutyl-2- benzothiazolesulfenamide) and DPG (N,N'-diphenylguanidine).
The VVOs with TMTD, ZDMC, MBTS and TBBS had shorter reaction times with increased level of accelerator.
The VVO synthesized with TBBS retained the same physical properties, regardless of loading.
0 phr, and the TBBS (BBTS) accelerator loading was from 0.
00 phr, while the TBBS (BBTS) accelerator levels were plotted against the 177 [micro]m 80 mesh MRP weight percent.
In these contour plots, the TBBS accelerator remains fixed at 1.
