Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer.It has the idealized formula [CH 2 CH(OH)] n.It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing.
Polyvinyl acetate (PVA, PVAc, poly ... or Elmer's Glue in the US, is a widely available adhesive used for porous materials like wood, paper, and cloth. An ...
Because of the instability of vinyl alcohol, the thermoplastic polyvinyl alcohol (PVA or PVOH) is made indirectly by polymerization of vinyl acetate followed by hydrolysis of the ester bonds (Ac = acetyl; HOAc = acetic acid): [8] n CH 2 =CHOAc → (CH 2 −CHOAc) n (CH 2 −CHOAc) n + n H 2 O → (CH 2 −CHOH) n + n HOAc
The thin wrapping portion of the pod which contains the liquid detergent is made from PVA, a dissolvable form of plastic also known as polyvinyl alcohol. This same PVA coating is also used in ...
Polyvinyl acetate (PVA), also known as "white glue", "hobby and craft" or “school glue” is non toxic, PH neutral, inexpensive, and easy to use, and is therefore the most commonly used type of wood glue. Joints should be tight fitting and clamped during curing for maximum strength.

Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
