What are Polymers? Understand Polymerization Reactions with Classification, Structure, Types, Properties and Uses of polymers. Learn to find the Molecular Mass of polymers with examples.
Of particular interest is the large number of chemical reactions developed for the covalent binding of enzymes via their nonessential functional groups to inorganic carriers such as glass, ceramics and iron, to natural polymers such as cellulose and Sepharose, and to synthetic polymers such as nylon...

This example relates to the use of polymers according to the invention as dispersing agents allowing the putting into aqueous suspension of natural calcium carbonate ground with no dispersant at a granulometry of which 73% of the particles have a diameter less than one micrometer determined by the...
Polymer, any of a class of natural or synthetic substances composed of very large molecules that are multiples of simpler chemical units. Polymers make up many of the materials in living organisms, and they constitute the basis of certain minerals and hu
plastics that are made up of polymers having only aliphatic (linear)carbonatoms in their backbone chains. All the commodity plastics listed above fall into this category. The structure of polypropylene can serve as an example; here attached to every other carbon atom is a pendantmethyl group(CH3...
Which class of polyester to choose? Polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) both belong to the polyester family. The use of alcohol resulting in an ester group makes these polymers distinctive. In chemical composition, PBT differs only slightly from PET. PBT has a hi...
He has a doctorate in Chemistry with additional general experience in mathematics, physics, biology, and business. Cite this lesson In this lesson, we will learn about two of the most important metals to commerce and industry today. Once you have learned about these two, you can challenge ...
In such a molecule each propylene repeating unit has the following structure: . More From Britannica major industrial polymers: Polypropylene (PP) Essentially, the molecule consists of a backbone of carbon atoms with attached hydrogen atoms; attached to every other carbon atom is a pendant methyl ...
Sodium Hexametaphosphate - (NaPO3)6 : Sodium Hexametaphosphate is also called Calgon. The formula for Sodium Hexametaphosphate is (NaPO3)6. It is a gathering of sodium polyphosphate polymers based on repeating NaPO3 units. To learn more about structure,
