Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
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.

semi-synthetic polymers are obtained from natural polymers by subjecting them to some chemical processes. eg: vulcanised rubber.
polymers add consistency or thickness to fluids. Because a number of additives can improve the filter cake such as bentonite, natural & synthetic polymer, asphalt and gilsonite.
Most are synthetic chemicals but you can find natural cleaning solutions like Mrs. Meyers also..they are more expensive though.
Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.

Also natural polymers exist.
Natural polymer: shellac, amber, natural rubber, cellulose Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.
no, both natural and synthetic rubber are polymers
No a cellulose is a natural polymer
A natural polymer would be rubber which is obtained from nature. A synthetic polymer would be polybutadiene which behaves like rubber.

is a spider web a polymer
Synthetic polymers contain linkages which are present in natural polymers also , for example nylon (a synthetic polymer) contains pep-tide (also called amide) linkage and proteins also contain the same linkage .. considering that protein is a naturally occurring polymer Btw , not sure if this is the only similarity .. :D
