The stretchiness of a polymer depends on its molecular structure. Polymers with long, flexible chains tend to be more stretchy because the chains can move past each other easily. In contrast, polymers with rigid or crosslinked structures are less stretchy because the chains are more constrained in their movement.
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.
Some polymers can have double bonds, such as in the case of some synthetic polymers like polybutadiene and polystyrene. These double bonds can affect the properties and reactivity of the polymer chains.
No, it is not always necessary to adjust the pH to neutral before adding polymers. Some polymers can work effectively in a wide range of pH levels. However, certain polymers may require specific pH conditions for optimal performance, so it is important to follow the manufacturer's recommendations.
The main source of raw materials for making polymers is petroleum or natural gas. These hydrocarbons are chemically processed to produce monomers, which are then polymerized to form different types of polymers. Additionally, some polymers can also be derived from renewable sources such as plant-based materials like cellulose or starch.
Major materials studied in material science include: Composites and nano-composites Carbon fibers Polymers and plastics Alloys and allotropes Supercritical fluids Glass and others Ceramics
The elasticity of a polymer depends on the cross-linking of its chains.
Elements do not contain polymers. It is the other way around. Organic polymers contain elements. These are usually C, O, H, N, Halogens and some others.
The elasticity of a polymer depends on the cross-linking of its chains.
on a molecular level they are different. the polymers they are made up of have different shapes
Synthetic polymers can react with other substances, but the extent to which they react depends on the specific polymer and the substance it is interacting with. Some synthetic polymers may undergo chemical reactions with certain substances, while others may not react at all. Compatibility and reactivity vary based on factors like chemical structure, functional groups, and environmental conditions.
Different polymers have different physical and chemical properties. This makes some polymers more suitable for particular applications than others. As a result, no one polymer is suitable for all applications.
There are some suspenders that are adjusted using buckles are buttons, so not all suspenders are stretchy.
It depends on the specific polymer and the production process involved. Some synthetic polymers can be relatively inexpensive to produce due to large-scale manufacturing processes, while others may be more costly due to factors such as raw material costs or specialized processing requirements.
No, only some phatts have reflecting material professionally sewn on them. Others are just made out of the same stretchy material with a plain logo on them, or in some cases nothing at all.
"It depends on what kind of restraints you have in mind. Some prefer rope and tie, others like stretchy rubber bands. It depends on the usage and what exactly you are restraining."
It's unequal; some people do well while others do not
Plastics, which are polymers plus some additives, are their main use.
