In the specific case of the organic coatings industry, alkali-soluble thickeners comprise one of the most important classes [7]. They usually are latexes, rich in carboxyl moieties, which come from (meth)acrylic acid, present in the composition of these emulsion-polymerized particles [8]. As these carboxyl groups are neutralized, the …

Non-traditional thickeners. In addition to traditional starches, there are new ways to thicken sauces and to change the texture of liquids. Some of these thickening agents work without heating and are simply blended with the cold liquid, such as modified starch or xanthan gum.

Zeolite-based catalyst hydrocracking of plastics is a potential strategy for mitigating the environmental impacts of plastic wastes and recycling valuable resources, but difficult mass transfer, low concentration of acid sites, and high cost are still barriers to their practical applications. In this paper, we report an excellent hydrocracking catalyst of …

The microstructures of two such thickeners have been determined. The structure of swollen microgels packed in intimate contact is postulated for an efficient thickener that confers pseudoplastic rheology. A less efficient thickener that confers viscoelastic rheology on aqueous systems is shown to be a true solution of polymer …

The thickening mechanism is explained by the formation of a hydrogen bond between a carboxyl group and a water molecule, known as hydration by the carboxylic acid moiety. This imparts structural viscosity through a three-dimensional network structure formed as a result of polymer thickeners being adsorbed to pigment particles.

This is evident from the high performance of Uni10M containing solutions compared to that of Uni6M. In the other hand, the thickening efficiency or thickener performance is reduced by decreasing the hydrophilic segment length (from 10,000 to 6000) in a constant hydrophobic segment length (C 18).
