Polyvinyl acetate Wikipedia

Celanese is a global leader in polyvinyl acetate homopolymer emulsions, often called PVAc or occasionally PVA homopolymers. Polyvinyl acetate is synthesized by the emulsion polymerization of vinyl acetate monomer (VAM). PVAc emulsions are best known for their use in wood glues or school glues due to their strong adhesion properties.

May 16, 2016· PVA, is a watersoluble polymer, usually with a high molecular weight. It is mostly linear with a high crystallinity. There are different grades of hydrolyzed PVA, where the partially hydrolyzed PVA (8590 %) is the most common one used in industrial emulsion polymerization of vinyl acetate.

Production Process of Redispersible Polymer Powder

In the emulsion containing PVA, aldehydes can also be added for PVA acetalization and then to reduce its water absorption. In addition to PVA, some other protective colloids with good water resistance can also be selected to ensure the water resistance of product, such as polyacrylic acids and modified polyacrylic acids.

Adhesives and emulsions Polyvinyl alcohol | PVA | PVOH

As an emulsifier, KURARAY POVAL™ and EXCEVAL™ are widely used as a protective colloid in the emulsion process. They are often used during the polymerization of vinyl acetate and vinyl acetate copolymer systems (vinyl acetate/ethylene, vinyl acetate/acrylic ester, etc.) to form highsolids emulsions with stability and adhesive properties.

How do I make PLGA microparticles? | Dolomite Microfluidics

The result is an oilinwater emulsion. This emulsion is then dried to form monodisperse PLGA microparticles. This process can be easily transferred to continuous flow droplet microfluidics. Microfluidic chips with 3D pore flowfocussing junctions can be used to create a wide range of droplet sizes for PLGA in dichloromethane (DCM) solutions.
