One of the distinguishing features of hydroxyethyl cellulose is its ability to dissolve in cold water, forming a clear, viscous solution. This solubility is primarily attributed to the hydroxyethyl groups that replace some of the hydroxyl groups on the cellulose backbone. The addition of these hydroxyethyl groups enhances both the hydrophilicity and the overall water-binding capacity of the polymer. The degree of substitution—meaning the number of hydroxyethyl groups introduced during synthesis—plays a vital role in determining the viscosity and solubility profile of HEC in water.

At the same time, the adsorption of quartz materials makes the polyvinyl alcohol gradually separated from the system. Without the hydrophilic protective colloid, the film which is insoluble in water and dispersible by RDP can not only be formed by one dispersion. In dry conditions, it can also be used in conditions of long-term water immersion. Of course, in non-basic systems, such as gypsum or filler-only systems, since polyvinyl alcohol is still partially present in the final polymer film, affecting the water resistance of the film, but these systems are not used for long-term water immersion. The occasion, as well as the polymer still has its unique mechanical properties, so it does not affect the application of dispersible polymer powders in these systems. With the formation of the final polymer film, a frame system composed of an inorganic and an organic binder, that is, a brittle-hard skeleton composed of a hydraulic material, and a film of the dispersible polymer powder formed on the gap and the solid surface are formed in the cured mortar. Flexible connection, this connection can be imagined as being connected to a rigid skeleton by a number of small springs. The tensile strength of the polymer resin film formed by the rubber powder is usually more than an order of magnitude higher than that of the hydraulic material, so that the mortar itself is strong. It is enhanced, and then the cohesion is improved. Due to the flexibility of the polymer, the deformation ability is much higher than that of a rigid structure such as cement, the deformability of the mortar is improved, and the effect of the dispersion stress is greatly improved, thereby improving the crack resistance of the mortar. As the amount of redispersible powder increases, the entire system develops toward plastics. In the case of high usage of redispersible powder, the quality of the mortar changes to become an elastomer, and the hydration product of the cement becomes a “filler”.
