Silk is natural, not a man-made polymer. The silk is mainly obtained from the cocoons of the Mulberry Silkworm (Bombyx mori). When the caterpillar forms a pupae, it encases itself in a cocoon of fine silk thread. Before the adult moth emerges, the cocoon is steeped in hot water to kill the developing moth inside. The cocoon is then unravelled and is combined with several other silk threads to produce a strong silk thread that can be used to produce silk fabric.

Why do natural polymers not pose as much of an issue in landfills as synthetic polymers Natural polymers are cheap to recycle and synthetic polymers are expensive to recycle. Natural polymers are expe?
Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
How are natural polymers and synthetic polymers similar?
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.
What is the definition of semi -synthetic polymer?
semi-synthetic polymers are obtained from natural polymers by subjecting them to some chemical processes. eg: vulcanised rubber.
Synthetic polymers that can be molded and shaped?
plastic
Is synthetic fiber made from plastic?
Some are but others are not made from plastic but from other synthetic polymers.
What is the basic chemical substance of all synthetic fibers?
Polymers
What are 5 polymers that are manufactured using technology prosses?
Virtually all synthetic polymers are used in industry.
Why are synthetic polymers often used in place of natural material?
Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
Is it true that polymers are all synthetic?
YES! polyvinyl chloride is a synthetic polymer. This is so because it is a polychain made up of repeated units of monomers. More specifically this plastic has the presence of HCl and ethyne within the organic compound. This is a type of a plastic used for various purposes such as insulation for electrical wires.

How is the polymer classified?
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.

What are some macromolocules?
Macromolecules are polymers. There are bio-polymers such as carbohydrates, proteins, lipids and DNA, and there are synthetic polymers such as plastics (polystyrene and polyvinylchloride) and synthetic fibres. Nylon and terylene are also considered macromolecules.
What is the definition of semi -synthetic polymer?
semi-synthetic polymers are obtained from natural polymers by subjecting them to some chemical processes. eg: vulcanised rubber.
How are nature polymers and synthetic polymers similar?
Nature polymers and synthetic polymers are both large molecules made up of repeating units called monomers. They both have high molecular weights and exhibit similar properties like flexibility, strength, and durability. Additionally, both nature and synthetic polymers can be engineered to have specific properties for various applications.
How are polymers and synthetic polymers similar?
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
Are pollymers synthetic?
Also natural polymers exist.
