What is the CAS number for Polyvinyl Alcohol?

Q: What is the CAS number for Polyvinyl Alcohol?

A: The CAS number for Polyvinyl Alcohol (PVA) is 9002-89-5. This unique identifier is used to reference the compound in scientific and regulatory contexts. It helps distinguish PVA from other chemicals.

How is Polyvinyl Alcohol (PVA) chemically structured?

Q: How is Polyvinyl Alcohol (PVA) chemically structured?

A: Polyvinyl Alcohol is a synthetic polymer derived from polyvinyl acetate through hydrolysis. Its structure consists of repeating vinyl alcohol units (–CH₂CHOH–). The degree of hydrolysis determines its solubility and properties.

What are common applications of Polyvinyl Alcohol?

Q: What are common applications of Polyvinyl Alcohol?

A: PVA is widely used in adhesives, coatings, and textile sizing due to its water-soluble and film-forming properties. It’s also employed in biomedical applications like drug delivery and contact lenses. Additionally, it serves as a binder in paper and packaging.

Is Polyvinyl Alcohol the same as Poly Alcohol?

Q: Is Polyvinyl Alcohol the same as Poly Alcohol?

A: No, "Poly Alcohol" is a broader term for polymers with hydroxyl groups, while Polyvinyl Alcohol (PVA) specifically refers to the polymer derived from vinyl acetate. PVA is a type of poly alcohol but has distinct chemical and functional characteristics.

Is Polyvinyl Alcohol safe for industrial use?

Q: Is Polyvinyl Alcohol safe for industrial use?

A: Yes, PVA is generally regarded as non-toxic and biodegradable, making it safe for industrial and consumer applications. However, proper handling guidelines should be followed to avoid inhalation or prolonged skin contact. Regulatory standards like OSHA guidelines apply for workplace safety.
