where \( m \) and \( n \) denote the degree of methylation and hydroxypropylation, respectively. This formula reflects the modified structure in which both the hydrophobic and hydrophilic properties coexist, allowing HPMC to interact with water in unique ways.

Biocatalysis has emerged as a promising alternative, where enzymes are employed to facilitate the etherification process, leading to more sustainable production practices.

Applications of HPMC

When HEC is added to water, its long polymer chains begin to interact with the water, creating a thickening effect. The chains of HEC become entangled and form a semi-solid network in the water phase. This network disrupts the flow of the liquid, resulting in increased viscosity. The thickening is primarily a result of the physical entanglement of the polymer chains rather than any chemical reaction, which differentiates HEC from many other thickening agents that may rely on gelling or coagulating processes.

- Inhalation and Ingestion HPMC is non-toxic; however, inhaling fine dust can irritate the respiratory tract. It is advisable to use appropriate respiratory protection when working with large quantities that may produce dust.

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”.
