Which of the following is a water insoluble polymer?
Several groups of water-insoluble polymers such as cellulose ethers, acrylic polymers and polyvinyl acetate-based polymers are used as release retarding coating materials.
Is an example of hydrophilic polymer?
An example of a polymer being hydrophilic due to hydrophilic segments is carboxymethyl cellulose and polyvinyl alcohol. These two polymers are used as thickening agents in ice cream as an example.
Which polymer is hydrophilic?
1 Natural hydrophilic polymers. Natural hydrophilic polymers include polysaccharides (e.g., dextran, alginate, chitosan, agarose, and pullulan) and proteins (e.g., albumin, gelatin, collagen, lectin, legumine, and viciline).
Which type of polymer is insoluble?

| Metal oxide | pHpzc |
|---|---|
| Al2O3 | 8.0–9.2 |
| TiO2 (P25) | 6.5–7.0 |
| ZrO2 | ~6.7 |
| SiO2 (stober) | < 3.0 |
What is water insoluble examples?
“Insoluble” generally means that a substance does not dissolve in water. Some examples include: sand, fats, wood, metals, and plastic.
Is h2o water-Soluble?

What is a hydrophobic polymer?
Hydrophobic (water-resistant) polymers are materials that are not soluble in water or other polar solvents and include acrylics, epoxies, polyethylene, polystyrene, polyvinylchloride, polytetrafluorethylene, polydimethylsiloxane, polyesters, and polyurethanes.
Which is not hydrophilic polymer?
Notably, there is a broad variety of hydrophobic polymers that is not considered to be hydrophilic at all, e.g., poly(styrene) or poly(methyl methacrylate). Contrarily, there are various polymers considered to be hydrophilic, e.g., poly(acrylamide) or poly(ethylene glycol) (PEG).
What does hydrophilic polymer mean?
Hydrophilic polymers are those polymers which dissolve in, or are swollen by, water. Many compounds of major technical and economic importance fall within this definition, including many polymers of natural origin.
What are water-soluble polymers examples?
Water-soluble polymers such as polyethylene glycol, polyacrylamides, polyacrylic acid copolymer, and polyvinyl alcohol are organic polymers that dissolve, disperse, or swell in water and consequently change the physical properties of aqueous systems undergoing gelation or thickening.
What are the example of insoluble and soluble?
We call substances that dissolve in water soluble. Sugar and salt are examples of soluble substances. Substances that do not dissolve in water are called insoluble. Sand and flour are examples of insoluble substances.
What is soluble and insoluble give example?
Salt, ethanol and sugar are examples of soluble substances and iron, wood, clothes, plastic are examples of insoluble substances.
