1. N-heterolong chain alkylacrylamide monomer
Appearance（25℃） | Translucent lotion | specific gravity（25℃，g/cm3） | 0.8~0.9 |
white oil（%） | 45~50 | boiling point（760mmHg，℃） | ≥120 |
PH | 4~6 | Solidifying point（℃） | ≤15 |
Actives（%） | 40~45 |
2. Features
1. Very suitable associative monomer for water-soluble ultra-high molecular weight polymers.
2. It has higher activity than methacrylate and methacryloyl monomers.
3. Compared with alkenyl ester monomers, it has higher acid and alkali resistance, so this monomer can be polymerized in a wide range of pH values, and polymer products can also be used in a wide range of pH values. Features beneficial for alkaline polymer flooding in oil fields.
4. Dosage: monomer × (2~4)%.
3. Application:
1. Production of oilfield associative polymers.
2. Others such as the production of coatings, textiles, adhesives, water-soluble polymer thickeners, etc.
4. Structural characteristics of associative polymer thickeners:
Associative thickeners are hydrophobically associative water-soluble polymers, which generally refer to water-soluble polymers with a small amount of hydrophobic groups on the hydrophilic macromolecular chain. Aggregation occurs due to the action, and the macromolecular chain produces intramolecular and intermolecular associations, which has a great impact on the rheology of the aqueous solution. Above the critical association concentration, a supramolecular structure dominated by intermolecular association is formed, which increases the hydrodynamic volume, so it has better thickening properties and is a new generation of thickeners. Since the water-soluble chain with relatively low molecular weight of the associative thickener has two or more lipophilic groups, the behavior of the surfactant in the aqueous solution can form micelles. However, the two lipophilic groups in the molecule are not necessarily in the same micelle, so they are connected to form a structure. The lipophilic groups in associative thickeners can adsorb emulsion particles or dye particles, which in turn enhances the structure. Furthermore, the microparticles bridged by the thickener macromolecules form a physical network (cross-linked) structure that can be gradually destroyed in the shear field, thus controlling the flow properties of the system. Such associations break off at high shear rates, reducing viscosity, and re-form after shear removal, restoring viscosity. However, the formation of the association takes time, so the recovery of viscosity is not as fast as that of cellulose, which gives a certain flow time, which is conducive to leveling and improvement of gloss.
