Polymers.
Polymers can be both depending upon which ones you are asking about. Polymer simply means "a chain of identical molecules linked together". Nonrenewable polymers would be plastics made from crude oil; renewable polymers would be cellulose and lignin in tree trunks.
Polymers are not made into crude oil. Crude oil is composed of a mixture of hydrocarbons that are naturally occurring in the earth's crust. However, polymers can be derived from crude oil through a process called polymerization, where small molecular units (monomers) derived from crude oil are chemically bonded together to form long chains known as polymers.
Large compounds composed of many smaller molecular subunits are known as polymers. Polymers are macromolecules formed by repeating units called monomers, which are linked together through chemical bonds. Examples of polymers include proteins, DNA, and plastics.
Some common polymers that contain nitrogen in their structure include nylon, protein-based polymers like collagen and keratin, and synthetic polymers like polyacrylonitrile. Nitrogen can be found as part of the backbone or within side groups of these polymers, contributing to their properties and functionalities.
Polymers are plastic. Thermosoftening is hard when it is cold and flexible when it is warm. Thermosetting is flexible when cold and hard when hotThermosetting plastics are polymers that, once heated, melted and moulded, cannot be re-moulded as the bond between their molecules are too strong. Thermosoftening plastics are polymers which can be re-moulded many times as the bonds between the molecules are very weak. Thermosetting plastics can only be shaped once. Thermosoftening plastics can be shaped and re-shaped many times. :) hope this is helpful x
Thermosoftening plastics soften and can be given any shape when hot. The different types thermosoftening plastics are Polyethylene, Polystyrene, Poly Vinyl Chloride, ABS plastics.
Plastics, which are polymers plus some additives, are their main use.
Thermosoftening plastics can be easily molded and reshaped when heated, making them versatile for various applications. They are also generally cheaper to produce compared to thermosetting plastics. Additionally, thermosoftening plastics tend to have better impact resistance and toughness.
Dehydration reaction.
Thermosoftening plastics are plastics that when heated, the polymers turn into a gooey kind of material which can then be put into a mould of whatever shape you wish the plastic to be. when it sets, you have your shaped plastic. thermosoftening plastics can be reheated and remoulded whereas thermosetting plastics cant be as the polymers for them, once moulded, cannot go gooey again because they have stronger chains between the polymers.
A polymer is a large molecule that consists of repeating structural units called monomers. Polymers can be natural or synthetic and have a wide range of properties and uses. Examples of polymers include proteins, DNA, plastics, and rubber.
Thermosoftening is when the bonds between molecules in a plastic are weak so that the plastic can easily soften. Thermosetting is when the bonds are strong so that the plastic can only be softened once and when it is, that is the only time that you can shape it.
Any plastic that if you put a flame to it , it will char/ burn/go black. NB A thermosoftening plastic is one , if heted, will just change shape. As a 'rule of thumb' opaque plastics are thermosetting; clear plastics are thermosoftening.
by recycling it and taking it to a factory
When polymers are broken down into monomers, the body uses those monomers for a number of activities. Some of them include protein construction and respiration. The process of polymers breaking down to monomers is called hydrolysis.WRITEN BY: oneofthem:
