What are the characteristics of branched polymers and how do they differ from linear polymers?
Branched polymers have side chains branching off from the main polymer chain, giving them a more complex structure. This branching increases their flexibility and reduces their crystallinity compared to linear polymers, which have a straight chain structure. Branched polymers also have lower viscosity and higher elasticity than linear polymers.
Are all polymers man made?
No, not all polymers are man-made. Some polymers can be found in nature, such as proteins, cellulose, and DNA. These natural polymers have unique properties and functions in living organisms.
What are some examples of polymers found in carbohydrates?
Some examples of polymers found in carbohydrates include starch, cellulose, and glycogen. These polymers are made up of repeating units of simple sugars like glucose.
Do polymers have double bonds?
Yes. Some polymers have double bonds, for example natural rubber - poly isoprene . See link for structure. However many polymers that are familiar do not polyethylene is (C2H4)n , polyvinyl chloride (C2H3Cl)n
What elements is plastic made of?
Most plastics contain carbon, hydrogen some contain oxygen , chlorine fluorine or nitrogen.
How do you alter characteristics of polymers?
Characteristics of polymers can be altered by: irradiation, treatment with oxygen or other chemicals, rising the temperature, using additives in the composition.
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.

What are the uses of polymers to mankind?
Plastics, which are polymers plus some additives, are their main use.
What are polymers called when they have start points and end points?
Polymers with distinct start and end points are referred to as "linear polymers." These polymers consist of long chains of repeating units (monomers) that form a continuous structure, allowing for specific functional properties. In contrast to branched or cross-linked polymers, linear polymers can display unique characteristics like improved tensile strength and flexibility, depending on their composition and molecular weight.
Are all polymers man made?
No, not all polymers are man-made. Some polymers can be found in nature, such as proteins, cellulose, and DNA. These natural polymers have unique properties and functions in living organisms.
What are example of Some polymers?
Molecules

Do Polymers come from plants?
Plants do make and use some polymers (e.g. starch, cellulose etc.), as do some animals (e.g. spider silk) but most of what we know as polymers are artificial (e.g. polyethylene, nylon etc.).
Name some polymers that are produced in nature?
There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.
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.
