The Polyethylene bottle containing drain cleaner. The PVC insulation on the electrical wiring. The ABS plastic case of the computer I am currently using. The Polypropylene food container with my take-away lunch in it. The Polyester fibres in the T-shirt that I am wearing.
Things like;
Shellac
Amber
Wool
Polystyrene
Silk
Natural rubber
Polystyrene
DNA
Silly Putty
Most Plastics
Proteins such as ; Hair, nails, tortoise shells
Things like metal, salt and compounds are NOT polymers, so dont get confused :)
Hope I helped~! \^3^\
Rubber
Cotton
Polyurethane
Teflon is a fun one: the macromolecules have no size limitations. If you have a piece of teflon tape 10 feet long, the macromolecules will also be 10 feet long.
a) Carbohydrates
b) Proteins
c)Lipids
d) Nucleic Acids
polyester,terylen,decaron, rayon and nylon .
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.
Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.

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).
cellulose Starch (amylose and amylopectin) proteins silk, spider webs are also poly-peptides (proteins) and are natural polymers polyhydroxyalkanoates (natural polyesters made by bacteria as food reserves) deoxyribonucleic acid (DNA) Natural Rubber Many polysacharides: Xanthan gum, B-Glucans, chitosan (from crab, shrimp, lobster shells) Enkephaline
Yes, that is correct. Proteins are natural polymers.
No a cellulose is a natural polymer
modified natural polymers are natural polymers which are altered in order to suit a particular purposeModified natural polymers are natural polymers which are altered in order to suit a particular purpose.

Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
Natural polymer: shellac, amber, natural rubber, cellulose Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.

For example thermoplastic and thermosetting polymers, natural and synthetic polymers.

from both plants and animals
Also natural polymers exist.
