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.

When borax is mixed with polyvinyl alcohol, a chemical reaction occurs that creates a polymer known as polyvinyl alcohol-borate complex. This polymer forms a network structure that gives the mixture a slimy and viscous texture, commonly known as "slime".
1 answer
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.

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.

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.

Polystyrene, polyvinyl alcohol, and polyvinyl acetate are not typically used in screen printing emulsions. Screen emulsions are usually made from light-sensitive compounds like diazo or photopolymer emulsions. These compounds provide the necessary properties for the emulsion to adhere to the screen and create a durable stencil for printing.

Sodium borate, also known as borax, acts as a crosslinking agent in the interaction between polyvinyl alcohol and other substances. It helps to form strong bonds between the polymer chains of polyvinyl alcohol, increasing its strength and stability. This crosslinking process is important in various applications such as adhesives, coatings, and films.
1 answer
Borax forms crosslinks with the polyvinyl alcohol molecules, creating a network structure that increases the material's strength and elasticity. This crosslinking also enhances the material's ability to absorb water and other substances.

Polyvinyl chloride (PVC) is commonly used in construction materials like pipes, fittings, and siding due to its durability and resistance to corrosion. It is also used in the production of window frames, credit cards, and medical equipment such as IV tubing.

Unlike many vinyl polymers, PVA is not prepared by polymerization of the corresponding monomer. The monomer, vinyl alcohol, almost exclusively exists as the tautomeric form, acetaldehyde. PVA instead is prepared by partial or complete hydrolysis (sometimes referred to in this case as saponification) of polyvinyl acetate to remove acetate groups.

Borax can crosslink polyvinyl alcohol (PVA) chains, forming a gel-like structure. This crosslinking strengthens the PVA chains, increasing the material's mechanical properties, such as elasticity and strength. Additionally, borax can improve the water resistance and thermal stability of PVA.

When sodium borate cross-links with polyvinyl alcohol, it creates a hydrogel. This hydrogel is a network of polymer chains that can absorb and retain large amounts of water. It is often used in biomedical applications, such as wound dressings or contact lenses, due to its biocompatibility and tunable properties.
1 answer
To remove polyvinyl alcohol applied as a stiffener in fabric, soak the fabric in warm water for about 30 minutes to dissolve the PVA. Gently massage the fabric to help break down the PVA, then rinse it thoroughly with water. Repeat the process if needed, or wash the fabric in a washing machine with mild detergent.

Hydrolysis of polyvinyl acetate can be done by treating it with a strong base, such as sodium hydroxide, in water. This reaction breaks down the polymer chain, resulting in the formation of vinyl alcohol and acetate ions. The acetate ions will further react with the base to form a salt.

Polyvinyl acetate is soluble in a number of organic solvents. Solubility of polyvinyl acetate is directly related to the volatility of the solvent; the more volatile the solvent, the more soluble the polyvinyl acetate. Some of the most common solvents, ranked in order from the most volatile to the least, are listed below.1. diethyl ether (very volatile, water miscible) 2. acetone (best solvent that is commonly used) 3. benzene (very toxic) 4. ethylene dichloride (very toxic, non-water miscible) 5. methanol (toxic, cumulative poison) 6. methyl ethyl ketone (MEK) (toxic) 7. ethanol (denatured alcohols may be toxic) 8. toluene (slightly toxic) 9. xylene (slightly toxic) 10. amyl acetate (slightly water miscible) 11.ethyl acetate
