PVA, or polyvinyl alcohol, is polar due to its hydroxyl (-OH) groups, which are capable of forming hydrogen bonds with water and other polar substances. These hydroxyl groups create regions of partial positive and negative charges, contributing to the molecule's overall polar character. The presence of these polar functional groups enhances PVA's solubility in water and its compatibility with other polar materials.

What is the chemical formula of PVA?
The chemical formula of polyvinyl alcohol (PVA) is (C2H4O)n, where n represents the number of repeating ethylene (C2H4O) units in the polymer chain.
Slime made from PVA and borax solution?
When PVA (polyvinyl acetate) is mixed with a borax solution, it undergoes a chemical reaction that creates a polymer network, resulting in the formation of slime. Borax acts as a cross-linking agent that links the PVA molecules together, creating a stretchy and gooey texture. This simple chemistry experiment is a popular way to create homemade slime for fun and educational purposes.
What is the use of cmc in pva emulsion?
CMC (carboxymethyl cellulose) is commonly used in PVA (polyvinyl acetate) emulsions as a thickening agent to control the viscosity of the emulsion. It helps improve the stability and consistency of the emulsion, making it easier to apply and providing better adhesive properties. Additionally, CMC can enhance the film-forming properties of the PVA emulsion, resulting in improved durability and performance.
How is polyvinyl alcohol made?
Polyvinyl alcohol (PVA) is made by the hydrolysis of polyvinyl acetate, which involves breaking down the acetate groups in polyvinyl acetate to form the alcohol groups in PVA. This process typically involves the use of a catalyst and water to facilitate the reaction. The degree of hydrolysis determines the properties of the resulting PVA polymer.
