A fluoropolymer is a fluorocarbon-based polymer with multiple carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and bases. The best known fluoropolymer is polytetrafluoroethylene. What is the use of fully fluorinated organic compounds? Hydrofluorocarbons (HFCs), organic compounds that contain fluorine and hydrogen atoms, are the mostRead More →
A polymer coating is a thin layered coating or paint made with polymers that provide superior adherence and protection from corrosion. A polymer is a molecule made by joining together many small molecules called monomers that are made up of a large number of similar units. Is Bakelite used inRead More →
Polyethylene is the simplest synthetic polymer. It’s made up of just one kind of monomer—ethylene, which is made of two carbon atoms and two hydrogen atoms. (Other polymers can be made of two or more different monomers.) Polyethylene is formed when many thousands of ethylene molecules are joined end toRead More →
DNA is called a nucleic acid because it was first found in the nucleus. We now know that DNA is also found in some organelles such as the mitochondria and chloroplasts. It is the DNA in the nucleus that actually controls the cell’s workings. Is nucleic acid A polymer? ARead More →
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other via covalent bonds to form larger molecules known as polymers. Are monosaccharides monomers or polymers? The simplest carbohydrates are called monosaccharides, or simple sugars. They are the building blocks (monomers) for theRead More →
While air dry clay sets with air, polymer clay sets by heat. … Polymer clay also won’t shrink while it is hardening, unlike air dry clay. Another important difference is that polymer clay is known to be more durable than air dry clay after baking. Once polymer clay is baked,Read More →
The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group. Is nucleic acid a polymer? A nucleic acid is a polymeric macromolecule made up ofRead More →
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. What is Guncotton in chemistry? Guncotton, or nitrocellulose (also known as trinitrocelluloseRead More →
