Methyl, tallow, bis-2-hydroxyethyl

Natural montroriUonite and organically modified MMT with methyl tallow bis-2-hydroxyethyl ammonium cations located in the silicate gallery (Cloisite 30B) were evaluted in starch-based nanocomposite [232]. It was observed that the TPS/ Cloisite Na-t nanocomposites showed higher tensile strength and thermal stability, better barrier properties to water vapor than the TPS/Cloisite 30B nanocomposites, as well as the pristine TPS, due to the formation of the intercalated nanostructure. Perez et al. [233] compared three different clays (Cloisite Na+, Cloisite 30B and Cloisite 10A) and found the best properties were achieved with Cloisite lOA due to their greatest compatibility with the matrix.

The organic modifier in Cloisite 30B is methyl, tallow, bis-2-hydroxyethyl, quaternary ammonium, where tallow is 65% CIS, 30% C16, and 5% C14. 

Structure-property relationships in crosslinked polyester-clay nanocomposites, prepared by dispersing methyl tallow bis-2-hydroxyethyl quaternary ammonium chloride-modified montmorillonite in prepromoted polyester resin and subsequently crosslinking using the methylethylketone peroxide initiator at room temperature and at several clay concentrations, were analyzed by X-ray diffraction combined with Transmission Electron Microscopy (TEM), thermal (TGA) and dynamic mechanical analyses as well as by the determination of mechanical and optical properties [158]. In all cases the formation of a nanocomposite and the morphology of a dispersion of intercalated/exfoHated aggregates of clay sheets in the resin matrix were confirmed (Fig. 17). hi the absence of reflection irrespective of clay concentration in the scattering curves for all the polyester-clay nanocomposites was ascertained.

PCL (commercial name CAPA 680) was kindly supplied from Solvay Interox Ltd, UK. The organoclay (commercial name Cloisite 30B) used in the preparation of nanocomposites was purchased from Southern Clay Products Inc, USA and was used as received. This organoclay consists of 2 1 montmorillonite (MMT) treated with methyl tallow bis-2-hydroxyethyl (MT2EtOT) as organic modifier.
