Polyvinyl acetate

Polyvinyl acetate is a synthetic thermoplastic polymer made by polymerizing vinyl acetate. Its film-forming and adhesive properties make it useful in glues, coatings, and paper products.

Vinyl acetate: Vinyl acetate is an organic compound used as the monomer for polyvinyl acetate and other polymers. Polymerization links this monomer’s molecules into polyvinyl acetate chains.
White glue: White glue is a water-based adhesive commonly formulated with polyvinyl acetate. It is the familiar household form of polyvinyl acetate adhesive.
Polymer: A polymer is a substance made of molecules composed of many repeating structural units. Polyvinyl acetate is one specific synthetic polymer.
Water resistance: Water resistance is a material’s ability to withstand wetting or water exposure without unacceptable change. Polyvinyl acetate adhesives can lose strength when exposed to moisture.
Free-radical polymerization: Free-radical polymerization is a chain-growth process in which reactive radicals add monomers successively. It is a common route for converting vinyl acetate into polymer chains.
Wood glue: Wood glue is an adhesive formulated to bond wood surfaces and joints. Many common woodworking adhesives use polyvinyl acetate emulsions.
Thermoplastic: A thermoplastic is a polymer that softens when heated and hardens when cooled, typically without permanent chemical crosslinking. This classification describes polyvinyl acetate’s response to heat.
Biodegradation: Biodegradation is the breakdown of substances by organisms or their enzymes. The persistence of polyvinyl acetate in waste depends on conditions and formulation.
Glass transition: Glass transition is the temperature range where an amorphous polymer changes between hard, glassy behavior and soft, rubbery behavior. It helps explain why polyvinyl acetate films soften with heat.
Bookbinding: Bookbinding is the craft and process of assembling pages into a durable book structure. Polyvinyl acetate adhesives bond paper, cloth, and board in many binding operations.
