For liquid detergent packaging, a suitable grade of PVA (Polyvinyl Alcohol) is often one with a high degree of hydrolysis, typically around 80-88%, combined with a medium to high molecular weight. This ensures good solubility in water and provides the necessary strength and durability to withstand handling and storage conditions. Additionally, grades with low viscosity are preferred for ease of processing and filling.

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.
Why is heat needed to assist in dissolving polyvinyl alcohol?
Heat is needed to assist in dissolving polyvinyl alcohol because it increases the kinetic energy of the solvent molecules, allowing them to break the intermolecular forces holding the polymer chains together. This results in a faster and more thorough dissolution of the polyvinyl alcohol in the solvent.
Does mixing borax and polyvinyl alcohol result in a chemical change?
Mixing borax and polyvinyl alcohol does not result in a chemical change. Instead, it forms a physical change known as cross-linking, where the borax molecules create bonds with the polyvinyl alcohol molecules to form a flexible slime-like material.
How do you clean off polyvinyl alcohol from lab glassware?
To clean off polyvinyl alcohol (PVA) from lab glassware, first rinse the glassware with warm water to dissolve the PVA, as it is water-soluble. If residue remains, soak the glassware in a solution of warm water and a mild detergent for 15-30 minutes. After soaking, scrub with a soft brush or sponge to remove any stubborn residues, and then rinse thoroughly with water. Finally, allow the glassware to air dry or dry with a lint-free cloth.

Who discovered polyvinyl alcohol?
Polyvinyl alcohol was first prepared by Hermann and Haehnel in 1924 by hydrolyzing polyvinyl acetate in ethanol with potassium hydroxide.
Is polyvinyl alcohol flammable?
No, polyvinyl alcohol is not flammable. It is a synthetic polymer that does not easily catch fire or burn.
Why is polyvinyl alcohol used to make hospital laundry bags?
Polyvinyl alcohol is used to make hospital laundry bags because it has good tensile strength, water solubility, and biodegradability. These properties make it suitable for holding soiled laundry in hospital settings where infection control and cleanliness are a priority. Additionally, polyvinyl alcohol can easily dissolve in water, making it convenient for washing the laundry without having to remove it from the bag.
How is polyvinyl alcohol made and what are the key steps involved in its production process?
Polyvinyl alcohol is made through the hydrolysis of polyvinyl acetate. The key steps in its production process include polymerization of vinyl acetate, hydrolysis of the polymer to form polyvinyl alcohol, purification, and drying.
Is polyvinyl alcohol really alcohol?
It is an alcohol. But the only alcohol that is in beverages is ethyl alcohol.
Why polyvinyl alcohol in vitamins?

Is polyvinyl alcohol ionic or covalent?
Polyvinyl alcohol is a covalent compound because it is made up of carbon, hydrogen, and oxygen atoms that are linked together through covalent bonds. It does not contain any ions.
