Understanding the Formula of Polyvinyl Alcohol

Polyvinyl alcohol (PVA) is defined by its distinctive chemical formula (C₂H₄O)_n, representing a synthetic polymer created through hydrolysis of polyvinyl acetate. The degree of hydrolysis (87-99%) directly impacts solubility and thermal stability, making precise formula control critical for industrial applications. Recent studies show optimized molecular configurations achieve 18% higher tensile strength compared to conventional formulations.

Technical Superiority in Polymer Science

PVA's hydroxyl-rich structure enables unique hydrogen bonding capabilities, delivering:

• Water solubility ranging from 4% to 30% aqueous solutions
• Oxygen barrier properties 50× superior to polyethylene
• Thermal degradation resistance up to 200°C

Manufacturers employ advanced polymerization techniques to control molecular weight (13,000-130,000 g/mol), directly affecting viscosity and film-forming characteristics.

FAQS on formula of polyvinyl alcohol

Q: What is the formula of polyvinyl alcohol?

A: The general chemical formula of polyvinyl alcohol (PVA) is (C₂H₄O)_n. It is a synthetic polymer derived from the hydrolysis of polyvinyl acetate. The "n" represents the number of repeating monomer units.

Q: What is the polyvinyl alcohol molecular formula?

A: Polyvinyl alcohol's molecular formula is (C₂H₄O)_n, where "n" denotes polymerization degree. Its structure consists of repeating vinyl alcohol units, though pure vinyl alcohol is unstable in monomeric form.

Q: How is the chemical formula of polyvinyl alcohol written?

A: The chemical formula of polyvinyl alcohol is written as (C₂H₄O)_n. This reflects its polymeric nature with hydroxyl (-OH) groups attached to alternate carbon atoms in the chain.

Q: What does the chemical formula of polyvinyl alcohol represent?

A: The formula (C₂H₄O)_n represents a chain of repeating units with two carbons, four hydrogens, and one oxygen per monomer. The hydroxyl groups make PVA water-soluble and highly adhesive.

Q: Why does polyvinyl alcohol have the formula (C₂H₄O)_n?

A: The formula (C₂H₄O)_n arises from the polymerization and hydrolysis of vinyl acetate. Each repeating unit retains a hydroxyl group, giving PVA its unique chemical properties.
