Siliconate treatments depend more on network formation than do silanes because the alkyl group
is normally a methyl (single carbon) and this does not lower the surface energy as much as higher alkyl groups
used on alkoxysilanes.
c] of composites produced using functional-ized MWCNTs decrease with the increase in alkyl group
carbon chain length.
EHEC, MEHEC and HM-EHEC are naturally derived multifunctional polymers with unique properties, including high surface activity, wide molecular weight range and various degrees of ethoxylation and alkylation, and alkyl group
The Waterloo group demonstrated that a carefully designed alkyl group
can be transferred specifically in the presence of the butyl groups on tin, and with no loss of stereochemistry.
and combinations thereof and an electrodepositable binder, the binder is comprised of resin(s) comprised of a phosphorous-containing group in which X is a hydrogen, a monovalent hydrocarbon or an oxygen atom having a single covalent bond to the phosphorous atom, and each oxygen atom has a covalent bond to a hydrogen atom, an alkyl group
, an aryl group, an alkylaryl group, an arylalkyl group, or the resin or one of the resins, with the caveat that at least one oxygen atom has a covalent bond to the resin or one of the resins; a carboxylate group separated by from 2-4 carbons from an ester group; and a tridentate amine ligand.
It is comprised of approximately 68% of an alkyl ethoxy sulfate surfactant wherein the alkyl group
has an average of 12-16 carbon atoms and the degree of ethoxylation is at least 3; from about 2-7% of a betaine surfactant; from about 2-7% of a hydroxysultaine surfactant; from about 0.
The antistatic coating film features a polymer with a polymerized unit represented by the following formula (1): wherein R1 and R2 each independently represent a hydrogen atom or a methyl group, R3 represents an alkylene group having 2 to 10 carbon atoms, R4 and R5 each independently represent an alkyl group
having 1 to 5 carbon atoms, R6 represents a hydrogen atom, an alkyl group
having 1 to 5 carbon atoms or a hydroxyalkyl group having 2 to 10 carbon atoms, and Y-represents a halogen ion, a halogenated alkyl ion, a nitrate ion, a sulfate ion, an alkyl sulfate ion, a sulfonate ion or an alkyl sulfonate ion.
However, with R = tert-butyl, a straight chain alkyl group
is preferred in the C-terminus position.
The electron donating nature of bigger pendant alkyl group
and the distribution of electron in polymer chain can also be inferred from the spectra.
3 (wherein R represents an alkyl group
having from 1 to 6 carbon atoms, a phenyl group or a cycloalkyl group), and carbon disulfide present in the resulting polymerization reaction mixture, thereby subjecting the 1,3-butadiene to 1,2-polymerization; and (b) cispolybutadiene obtained by a step of adding the foregoing cis-l,4-polymerization catalyst, thereby subjecting the 1,3-butadiene to cis-l,4-polymerization anda rubber composition containing the resulting rubber.
has been granted a patent for a multilayer coating in which a plurality of photocurable resin cured films are layered, wherein at least two adjacent layers comprise the same hindered phenol antioxidant in different amounts, and wherein the antioxidant has at least one hindered phenol group, the hindered phenol group containing none or only one sterically hindered alkyl group
selected from the group consisting of an i-propyl group, an i-butyl group, and a tert-butyl group and wherein the adjacent layers comprise urethane meth(acrylate), wherein the multilayer coating further is comprised of an amine compound; wherein the amine compound is present in the multilayer coating to prevent the generation of hydrogen gas.
0% of a C8 to C10 alkylpolyglucoside wherein the alkyl group

The first monomer unit has the formula: R1, R2 and R3, which are independently selected from the group consisting of hydrogen a C1-3 alkyl group
and a halogenated C1-3 alkyl group
It seems that the type of alkyl group
in the alkyltriethoxysilane used in this system has no effect on the particle size.
The salt of organic sulfonic acid comprises one or more selected from the group consisting of alkali salts of alkyl sulfonic acid with alkyl group
with 6-22 carbon atoms, alkali salts of alkyl aryl sulfonic acid with alkyl group
