What is the sourceof small molecules which are used in making synthetic polymers?
Small molecules used in making synthetic polymers are typically sourced from petrochemicals, such as ethylene and propylene, which are derived from crude oil or natural gas. These small molecules undergo polymerization reactions to form long chains of repeating units, creating synthetic polymers like polyethylene and polypropylene.
Is there any subgroups of polymers?
Yes, polymers can be broadly categorized into natural and synthetic polymers. Synthetic polymers can further be classified based on their chemical structure and properties, such as thermoplastics, thermosets, elastomers, and fibers. These classifications help in understanding the different characteristics and applications of polymers.
Are cellulose molecules examples of synthetic polymers?
No, cellulose molecules are not examples of synthetic polymers. Cellulose is a natural polymer found in the cell walls of plants and is composed of repeating glucose units. Synthetic polymers, on the other hand, are man-made polymers created through chemical processes.
What is the difference between a bio-polymer and a synthetic polymer?
Bio-polymers are derived from renewable resources, such as plants and animals, and are biodegradable, while synthetic polymers are man-made from fossil fuels and are not biodegradable. Bio-polymers have a lower carbon footprint and are more environmentally friendly compared to synthetic polymers.
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.
Why are synthetic polymers often used in place of natural material?
Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
Why do most plastics remain in landfills for a long time?
because the plastic synthetic polymers are based on hydrocarbons, the polymers do not decompose easly.
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 are biodegradable, meaning they can be broken down by bacteria and other organisms in the environment. This process helps to reduce the amount of natural polymers going to landfills. Synthetic polymers, on the other hand, are not easily biodegradable and can persist in the environment for a long time, contributing to landfill waste issues.
How is the polymer classified?
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
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.
Are cellulose molecules examples of synthetic polymers?
No, cellulose molecules are not examples of synthetic polymers. Cellulose is a natural polymer found in the cell walls of plants and is composed of repeating glucose units. Synthetic polymers, on the other hand, are man-made polymers created through chemical processes.
How are synthetic fibers produced?
Synthetic fibers are produced through a process called polymerization, where small molecules are chemically bonded together to form long chains of polymers. These polymers are then spun into fibers through processes like spinning or extrusion. Examples of synthetic fibers include polyester, nylon, and acrylic.
What is the difference between a bio-polymer and a synthetic polymer?
Bio-polymers are derived from renewable resources, such as plants and animals, and are biodegradable, while synthetic polymers are man-made from fossil fuels and are not biodegradable. Bio-polymers have a lower carbon footprint and are more environmentally friendly compared to synthetic polymers.
