A polymer is a large molecule (macromolecule) composed of repeating structural units. These subunits are typically connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of natural and synthetic materials with a wide variety of properties.

What are the properties and applications of polymethylene in the field of polymer chemistry?
Polymethylene is a type of polymer with repeating methylene units. It is known for its flexibility, low density, and resistance to chemicals and moisture. In polymer chemistry, polymethylene is used in various applications such as in the production of plastic films, fibers, and coatings. Its properties make it suitable for use in packaging materials, textiles, and automotive parts.
What is end group analysis in polymer?
End group analysis in polymer chemistry refers to the process of identifying and quantifying the end groups of a polymer chain. This analysis provides information about the structure and properties of the polymer, as well as the effectiveness of the polymerization process. Techniques such as spectroscopy and chromatography are commonly used for end group analysis.
What is dead polymer?
Dead polymer is said to be it is incapable of further growth by monomers. The polymer is originally composed by heavy molecules, monomers. When there is no longer active polymerization, the polymer is dead. HIMANSHU SINGH M.Sc.-Industrial chemistry up india MO-09839358172
What does resin means in polymer chemistry?
Resin in polymer chemistry refers to a solid or highly viscous substance produced by plants or synthesized chemically. It acts as a binder or matrix in composite materials and can be used to make various types of plastics and adhesives. Resins are made up of long-chain molecules called polymers, which give them their unique properties.
What is Tg?
In chemistry, Tg is the glass transition temperature of an amorphous polymer. It is the individual polymer's fixed temperature at which point it either becomes flexible when the actual temperature of it is higher than the Tg, or it becomes rigid, when the actual temperature is lower than its Tg. An amorphous polymer is one whose structure is tangled. Tg is the cause of polymer items breaking. Leave a plastic bucket outside in winter and it can easily break in its rigid state, frozen or not.
How do you use the word polymer in a sentence?

What does polymer chemistry deal with?
Polymer chemistry is the study of organic (natural) and synthetic (produced) polymers. Polymer was first discovered in the 19th century and since then has grown into a branch of science that produces everything from bandages to tires.
