Figure 17-12. Biocides for hydraulic fracturing fluids 2-mercaptobenzoim-idazole, 2-mercaptobenzothiazole, 2-mercaptobenzoxazole, 2-mercapto-thiazoline, 2,5-dimercapto-1,3,4-thiadiazole, and 2-imidazolidinethion.

Figure 2. Nitrogen adsorption isotherms at 77K for the OMM samples with multifunctional mercury-specific ligands 1-benzoyl-3-propylthiourea (OMM-1 and OMM-2), 2,5-dimercapto-1,3,4-thiadiazole (OMM-3) and the corresponding differential pore size distributions. OMM-a, OMM-b and OMM-c refer to the calcined MCM-41, MCM-48 and SBA-15 samples, respectively. For clarity the isotherms are offset vertically by 1000 ccSTP/g for OMM-a and OMM-1 samples and by 500 ccSTP/g for OMM-b and OMM-2 samples. The PSD plots are offset vertically by 2 ccg 1nm 1 for OMM-a and OMM-1 and by lccg-1 nm"1 for OMM-b and OMM-2 samples.

Poly(oxyethylene) combinations with various other comonomers [46], are of interest as solid polymer electrolytes after complex formation with Li(I) (complexation with Na(I), K(I), Mg(II), Ba(II), etc. has also been studied) [1,5,46-48]. The synthesis is carried out by direct interaction of the ligand and metal ions in solution or, if cross-linked poly(oxyethylene) is employed, by immersing the polymer ligand into a solution of the metal salt. Poly(oxypropylene), modified polysiloxanes, cross-linked phosphate esters and ethers [46,49,50], and structurally different ligands such as 2,5-dimercapto-1,3,4-thiadiazol-polyaniline [51] have also been used as polymer ligands, The developments in this field are reviewed in [46], In this review the segmental motion of Li(I) in a poly(oxyethylene) is described as shown in Fig. 5-4.

This article describes the performance of a new curative for polychloroprene, a derivative of 2,5-dimercapto-1,3,4-thiadiazole (DMTD). This curative provides long Mooney scorch times, rapid cure rate resulting in short cure times and an exceptionally flat cure plateau. Other performance characteristics are presented, including the effect of other additives in a typical polychloroprene formulation. 5 refs.
