The preparation of functional nanocomposites by dispersion of a synthetic lamellar α‐ZrP within a styrene/butadiene random copolymer during melt compounding is described. It is shown how the physical and chemical incompatibility of filler and polymer can be overcome, and problems arising from the low viscosity ratio between slurry and polymer matrix are discussed. The aqueous phase can easily be eliminated at the end of the process. The dispersion of the ZrP requires the use of intercalants, and alkylamines were used for this purpose. XRD and TEM are used to characterize the degree of organization of ZrP in the slurries and in the matrix. DMA helps to understand the origin of the limited reinforcing effect.
A simple one-pot synthesis of 3-alkyl-4-methyl-2-phenylimino-2,3-dihydrothiazoles from the reaction of phenylisothiocyanate, primary alkylamines and 2-chloro-1,3-dicarbonyl compounds under solvent-free conditions is described. 相似文献
