Ribonucleic acid
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).
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.
Yes
semi-synthetic polymers are obtained from natural polymers by subjecting them to some chemical processes. eg: vulcanised rubber.
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.
Yes, that is correct. Proteins are natural polymers.
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.

from both plants and animals
Also natural polymers exist.
Natural polymer: shellac, amber, natural rubber, cellulose Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.
Yes
no, both natural and synthetic rubber are polymers
