Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
Polymers.
Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
Yes, that is correct. Proteins are natural polymers.
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
Rubber is a natural polymers with elastic and plastic type behavior. It is found in nature and extracted from trees. PET (soda bottles) Polyethylene Terephthalate is a synthetic polymer and not found in nature.
There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.
Monomers hook up to form polymers. There is a link below that will lead you to the Wikipedia post on polymers.Water is also produced, this is a condensation reaction.
Natural polymers are discussed in other web pages and include:Proteins - silk, collagen, keratin.Carbohydrates - cellulose, starch, glycogenDNA - RNAOther Natural polymers: Rubber (hydrocarbon base) and silicones (alternating silicon and oxygen).
Also natural polymers exist.
Natural polymer: shellac, amber, natural rubber, cellulose Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.
