Product Description

Poly(vinyl acetate) (PVAc)

Poly(vinyl acetate) (PVAc) is a widely used thermoplastic polymer known for its adhesion properties, flexibility, and water resistance. It is synthesized via free-radical polymerization of vinyl acetate and has a glass transition temperature (Tg) of approximately 28–32 °C, which contributes to its utility in emulsion and coating systems.

Key Properties

Polymer type: Poly(vinyl acetate) (PVAc)
Polymerization: Free-radical polymerization of vinyl acetate
Glass transition temperature (Tg): ~28–32 °C
Performance profile: Adhesion, flexibility, water resistance
Typical use: Emulsions, coatings, and formulation research

Applications

Adhesives: Main component in wood glues, paper adhesives, and emulsion-based formulations.
Coatings and paints: Provides film-forming properties in architectural coatings.
Binder for textiles and paper: Used in fabric finishing and paper coatings.

FAQs

Common questions about Poly(vinyl acetate) (PVAc).

What is poly(vinyl acetate) used for?

PVAc is commonly used in adhesive formulations (including wood and paper adhesives) and in coating systems where film formation and flexibility are important.
How is PVAc related to poly(vinyl alcohol) (PVA)?

Poly(vinyl alcohol) is typically produced by hydrolyzing poly(vinyl acetate). In other words, PVAc can be a precursor polymer used to make PVA through chemical conversion.
Is PVAc water soluble?

PVAc is generally not considered water soluble. It is often used in water-based (emulsion) formulations, where the polymer is dispersed rather than dissolved.
What does “film-forming” mean in practice?

“Film-forming” refers to the ability of a polymer to create a continuous, coherent layer after application and drying/curing of a formulation, which is a key property for many coatings and adhesive systems.
