Among their topics are characterizing a novel polymeric drift control agent in a vertically oriented low-speed wind tunnel, the impact of spray adjuvants on the physical properties of the solution and size of the spray droplet, using modified trisiloxane alkoxylates to control trisiloxane alkoxylate foam in superspreaders: a mechanistic study, structure-performance relationships a variety of aromatic polyetheramide comb polymer dispersants, and visualizing urea treatments using micro-X-ray fluorescence spectrometry.
PolyPEG is a novel low viscosity comb polymer for extending the duration of action of biopharmaceuticals.
(44) This comb polymer has a measurable extensional viscosity, although at higher concentrations than the high-[M.sub.v] HEC.
Early on this work, the molecular orientation and surface morphology of monolayer and LB multilayers for corresponding acrylate comb polymer was studied on in-plane XRD, AFM, and so on [31, 43].
In the cross section of the surface in molecular resolution images along the dashed line of copolymer system, the distance between fluorocarbon side-chains in the sea region was estimated the range from 4.9 to 5.4 [Angstrom], which well-corresponded to the value of the two-dimensional short spacing of this comb polymer measured by WAXD in the bulk state [31, 43], while the distance between hydrocarbons in the island region exhibited the range from 3.9 to 4.3 [Angstrom].
Is it a commodity anionic polymer, an electrosteric comb polymer, or a formulated product?
Conventional dispersants including an acetylenic diol surfactant, a styrene acrylate polymer, and a styrene maleic anhydride modified with a polyether comb polymer were from different dispersant suppliers.
These include multifunctional dispersants, such as the block and comb polymer surfactant available today.
The comb polymers, for carry on a large scale branched units in the polymer chain, affected substantially physical properties such as viscosity and solubility.
