Why are synthetic polymers often used in place of natural material?
Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
Plastic synthetic fabrics and synthetic rubber are composed of chemicals derived from what?
well the answer is non other than Petroleum
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 is the polymer classified?
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
What are 2 benefits associated with the use of synthetic polymers?
Polymers are used in our lives as polythene is used in shopping bags, They are used in for different things as-well, for example NYLON in suitcases and bags Polyvinyl-acetate in plastic bottles and utensils There are many Different Polymers The clothes we were are made out of polyester
What are the three main types of macromolecules or polymers in living organisms?
The three main types of biological polymers that living organisms produce are polysaccharides, proteins, and nucleic acids.
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 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.
Why do synthetic polymers have recycling numbers?
Synthetic polymers have recycling numbers to indicate the type of plastic they are made of and help with sorting and recycling processes. The numbering system, known as resin identification codes, was introduced to standardize recycling efforts and determine the appropriate recycling method for each polymer. This allows for efficient sorting and recycling of different types of plastics, reducing waste and promoting circular economy practices.
What are the two different types of polymers?
1. Polyethylene.2. Polyester.These are the main two types of plastics;there may be many more plastics lying on the grounds of this big chunk of land[EARTH].
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.
