摘要:
A compound of the formula: (I) is provided, where R is selected from CF3, F, and H, and m is an integer from 1 to 22. The compound may be prepared by reacting a first reactant with a second reactant in a solution, where the first reactant is a 2,4-dichloro-2,4,6,6-tetra(aryloxy)-1,3,5-triaza-2,4,6-triphosphorine, and the second reactant is a perfluoropolyether of the formula CF3CF2CF2O(CF2CF2CF2O)mCF2CF2CH2OH. The aryloxy is selected from 4-(trifluoromethyl)phenoxy (p-CF3—C6H4O), 4-fluorophenoxy (p-F—C6H4O), and phenoxy (C6H5O). The first reactant may be prepared by reacting 2,2,4,4,6,6-hexachloro-1,3,5-triaza-2,4,6-triphosphorine with a phenoxide. The compound may be used in a lubricant for lubricating a surface. The lubricant may be applied to a recording surface in a magnetic recording device including a recording medium.
摘要:
A polymer composite composing a polymer matrix having, dispersed therein, a nano clay in combination with a crosslinking promotor. In method form, the invention relates to a process for enhancing the mechanical properties of a polymer composite, comprising supplying a polymer matrix, combining the matrix with a nano clay and a crosslinking promotor and crosslinking.
摘要:
A copolymer for modifying rheology is formed of monomer units consisting essentially of at least one first monomer unit comprising a polyhedral oligomeric silsesquioxane having an ethylenically unsaturated radical; at least one second monomer unit comprising an unsaturated oligo-poly(dimethyl siloxane)(meth)acrylate; and a sufficient amount of at least one unsaturated water-soluble monomer, such that the copolymer is soluble in water. A composition may comprise an electrolyte and the copolymer. The rheology of an environment comprising an electrolyte may be modified by adding the copolymer to the environment.
