TLDR
In this article, novel amphoteric emulsifiers are disclosed for solventless and solvent containing mixing grade, oil-in-water anionic and cationic bituminous emulsions.Abstract:
Novel amphoteric emulsifiers are disclosed for solventless and solvent containing mixing grade, oil-in-water anionic and cationic bituminous emulsions, which emulsifiers are the modified reaction products of polyamines with certain polycarboxylic acids and sulfonated carboxylic acids. Modifications are carried out by reacting the nitrogen-containing intermediate with formaldehyde and sodium sulfite or bisulfite, chloroalkane sulfonic acid salts, γ-propane sultone, chloroalkane phosphonic acids, acrylic acid, fumaric acid, maleic acid and chloroethanoic acid.read more

Method for producing bitumen compositions
TL;DR: In this article, the authors proposed bituminous paving compositions suitable for use in paving applications containing bitumen emulsion of performance-grade bitumen that is substantially free of volatile solvents and made by controlling temperature-dependent interfacial rheology through the use of selected emulsifiers.

Emulsifiers for bituminous emulsions
TL;DR: In this paper, reaction products of polyamines with certain polycarboxylic acid anhydrides are modified by reacting with formaldehyde and sodium sulfite or bisulfite, formaldehyde, and phosphorus acid, haloalkane sulfonic acid salts, γ-propane sultone, acrylic acid, fumaric acid, maleic acid and Haloalkanoic acids.
Patent
Reflective asphalt emulsions and method
TL;DR: A reflective asphalt emulsion is formed by dispersing asphalt into a slurry of colloidal clay at high shear and thereafter blending titanium dioxide and diatomaceous earth filler, and optionally acrylic latex, at low shear into the emulsion of clay and asphalt to form a white to light gray emulsion having a soft consistency and good shelf life.

Selective reaction of fatty acids and their separation
TL;DR: In this paper, a process for making a DICARBOXYLIC ACID having 21 CARBON ATOMS from FATTY ACIDS is described, which is then separated by separating into an OLEIC-type ACID and a G21 DCA.
