Molecules
There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
Yes. Some polymers have double bonds, for example natural rubber - poly isoprene . See link for structure. However many polymers that are familiar do not polyethylene is (C2H4)n , polyvinyl chloride (C2H3Cl)n
While plastics are used as a common example of polymers, there are many other materials which are also polymers. Polymers include:anything plasticproteins, such as hair, nails, tortoise shellcellulose in paper and treesDNAsilly puttyrubber

No, it is not always necessary to adjust the pH to neutral before adding polymers. Some polymers can work effectively in a wide range of pH levels. However, certain polymers may require specific pH conditions for optimal performance, so it is important to follow the manufacturer's recommendations.
Plastics, which are polymers plus some additives, are their main use.
Some common polymers that contain nitrogen in their structure include nylon, protein-based polymers like collagen and keratin, and synthetic polymers like polyacrylonitrile. Nitrogen can be found as part of the backbone or within side groups of these polymers, contributing to their properties and functionalities.
No, not all polymers are man-made. Some polymers can be found in nature, such as proteins, cellulose, and DNA. These natural polymers have unique properties and functions in living organisms.
Some examples of polymers found in carbohydrates include starch, cellulose, and glycogen. These polymers are made up of repeating units of simple sugars like glucose.
For example the formula of ethylene is C2H4.
Plants do make and use some polymers (e.g. starch, cellulose etc.), as do some animals (e.g. spider silk) but most of what we know as polymers are artificial (e.g. polyethylene, nylon etc.).
