Why can't polymers be analysed by gas chromatography?
Polymers are too large and complex to be vaporized and separated by gas chromatography. Gas chromatography is typically used for analyzing small molecules with low molecular weight, as they can be vaporized and pass through the column more easily for separation. Polymers, being much larger, tend to degrade or decompose when subjected to the high temperatures of the gas chromatography column.
What polymers are derived from acetylene gas is called polychloroprene?
Acetylene
Does gum dissolve in water?
gum is made up of billions of long molicule chains called polymers. in a normall state, the polymers curl like a spring. when stretched, the "springs' unwind. when they are cold, the polymers wind up tighter and loose most of their elastisity
Is plastic gas?
No, plastics and polymers are solids but they also may be liquid at high enough temperatures.
What the main source of raw material for making polymers?
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.
What oil is plastic made from?
The feedstock for polymers chemistry may be petroleum, methane gas, coal, plants.
What is gas fading of polymer?
Gas fading of polymers refers to the phenomenon where exposure to certain gases, such as ozone, nitrogen oxides, or sulfur dioxide, causes the polymer material to degrade or discolor due to chemical reactions with the gas molecules. This can result in a loss of mechanical properties, such as strength and flexibility, and a change in appearance of the polymer material. To prevent gas fading, polymers can be formulated with additives that act as inhibitors against the damaging effects of the gases.
Where do the starting materials for most polymers come from?
Starting materials for most polymers come from petrochemical sources such as crude oil or natural gas. These raw materials are refined and processed to extract the building blocks needed to create polymers through polymerization reactions. Additionally, some polymers can also be derived from renewable sources such as plants or animals.
Is plasma a polymer?
No, plasma is ionized gas. Under the conditions that form plasma most polymers would break down.
What state is called the state of gas?
Gas state of water is steam
What state is called the gas state?
Gas state of water is steam
Which change of state do drying clothes undergo?
The clothes themselves generally don't undergo any change of state (clothes made of certain polymers in a dryer may undergo a second-order state change by going through their glass transition temperature).
