44) This comb polymer has a measurable extensional viscosity, although at higher concentrations than the high-[M.
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].
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.
Furthermore, the comb polymers containing various fluorocarbon side-chains with various lengths and fluorine atoms at the [omega]-position were obtained using postpolymerization of these corresponding monomers irradiation of [.
a poly (acrylic acid), a lignosulphonate, and a comb polymer (consisting of a polycarboxylate backbone modified with sulphonate groups and grafted polyoxyethylene chains) as dispersants for highly concentrated aqueous alumina suspensions have been investigated by Palmyqvist et al.
Once the optimum molecule was achieved, its performance in pigment concentrates with and without a resin was compared to other conventional dispersants such as a styrent acrylate copolymr, an acetylenic diol surfactant, and a styrene maleic anhydride comb polymer modified with a polyether.
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.
The adsorbed layer thickness of a comb polymer can be added to the volume fraction of the solid particles, [phi], (calculated solid loadings), to give an effective volume fraction, [[phi].
