1. Alkylation The cellulose is first treated with methyl chloride or methyl bromide in the presence of a base, typically sodium hydroxide. This step introduces methyl groups to the cellulose backbone, thus yielding methylcellulose. The extent of methyl substitution can be controlled by adjusting the reaction conditions such as time, temperature, and concentration of reagents. The degree of substitution (DS) is a critical parameter that dictates the solubility and other properties of the resulting HPMC.
Furthermore, RDPs are known for their ability to improve resistance to chemicals and weathering. In construction projects that involve exposure to harsh environmental conditions, such as coastal areas or regions prone to heavy rainfall, the use of RDPs can significantly enhance the longevity of structures. They provide a protective barrier that helps prevent damage from water intrusion, freeze-thaw cycles, and other environmental stressors.
