different erasers are different materials so both. some are made from rubber that comes from trees and others are made syntheticly
It is a synthetic addition polymer.
is a spider web a polymer
Both the polymers have a repeating structure which is the basic definition of polymer.
No - it is a synthetic polymer and it is not a natural polymer like cotton which has excellent absorption qualities.
No a cellulose is a natural polymer
it is a synthetic polymer. depends on how you made it
It is a synthetic addition polymer.

A natural polymer would be rubber which is obtained from nature. A synthetic polymer would be polybutadiene which behaves like rubber.
neither

natural, starches are a form of sugar, potatos have a form of starch. I'm sure there are also some synthetic ones as well.
Not truly. Neither is it a natural fibre. It is manufactured from cellulose, which is a naturally occurring polymer. It's regarded as "semi-synthetic", or "artificial".
No - it is a synthetic polymer and it is not a natural polymer like cotton which has excellent absorption qualities.

rubber
