Polystyrene chains (molecular weight samples from38 kDa to 310 kDa) confined in AAO nanopores as large as the sizeof the pore diameters (from 35 to 180 nm) are probed, revealing theinvariance with respect to the bulk-like conformation for polystyrenechainsup to 301 kDa confined downto 35 nm...
Poly(acrylic acid) or PAA (CAS number 9003-1-04) is a type of polymer. The monomer of poly(acrylic acid) is Acrylic Acid. In a water solution at neutral pH, many of the side chains of PAA will lose their protons and acquire a negative charge. For a description of unrelated compounds...
In DNA, the two chains are held together by what bond between the bases? What is a single-ring nitrogenous base found in DNA called? What DNA base is complementary to thymine? Which nitrogenous base is normally present in DNA but absent from RNA? a) cytosine b) thymine c) guanine ...
Next, the polymer is dissolved in sulfuric acid to create a liquid crystalline solution. The solution is then spun into fine, naturally yellow or dye-infused continuous filament yarns by a wet-spinning process. These fibers are completely crystalline, with molecular chains running parallel to the ...

What is an organic acid and polymer composed of four nitrogenous bases (adenine, thymine, cytosine, and guanine) called? It is the genetic material of most organisms and exists as a double-stranded molecule held together by hydrogen bonds. Which...
Like other polymers, spandex is made from repeating chains of monomers that are held together with an acid. Early in the spandex development process, it was recognized that this material is highly heat-resistant, which means that notoriously heat-sensitive fabrics like nylon and polyester are impro...
A polymer is made up of very large chains of molecules. The glue used in slime comprises long chains of polyvinyl acetate molecules (that’s why we recommend PVA glue). These chains slide past one another fairly easily, that keeps the glue flowing. Chemical bonds are formed when you mix ...
A polymer is achemical compoundwith molecules bonded together in long, repeating chains. Because of their structure, polymers have unique properties that can be tailored for different uses. Polymers are both man-made and naturally occurring. Rubber, for example, is a natural polymeric material that...
These chains of monomers are also called macromolecules. Most polymer chains have a string of carbon atoms as a backbone. A single macromolecule can consist ofhundreds of thousands of monomers, according to the Polymer Science Learning Center. ...
