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 .
In particular, the authors find five patterns: skimming (40% frequency), penetration (20% frequency), and three variants of market-pricing patterns (60% frequency), where new products are launched at market prices. Skimming pricing launches the new product 16% above the market price and subsequently increases the price relative to the market price.
Selling a product at a high price, and sacrificing high sales to gain a high profit is therefore "skimming" the market. Skimming is usually employed to reimburse the cost of investment of the original research into the product: commonly used in electronic markets when a new range, such as DVD players, are first sold at a high price.

Polyvinyl alcohol −[HOCHCH 2]−: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules. [12]
[6] [10] This strategy is often used during the early stages of the business or before it enters the market, in order to prove the market existence and show market size for its products or services, also to gain an understanding to the number of competitors and how well they are doing.

The development of plasterboard (a sandwich of gypsum plaster between two sheets of paper) dates back to the late nineteenth century in the US. The first patent was granted in 1894 but it was not until an American, Frank Culver, persuaded his new employer, Thomas McGhie and Sons, to buy a plasterboard plant from the US that this new product was introduced to Britain.
