What is this polymer?

A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms and are the basis of many minerals and man-made materials.

What are 3 properties of polymers?

Heat capacity/ Heat conductivity. The extent to which the plastic or polymer acts as an effective insulator against the flow of heat.

  • Thermal expansion. The extent to which the polymer expands or contracts when heated or cooled.
  • Crystallinity.
  • Permeability.
  • Elastic modulus.
  • Tensile strength.
  • Resilience.
  • Refractive index.
  • What are physical properties of polymers?

    Physical properties of polymers include molecular weight, molar volume, density, degree of polymerization, crystallinity of material, and so on.

    Why do different polymers have different properties?

    Why do different polymers have different properties? Answer: They have different chemical compositions (different monomer units), different structures, different ways of being fabricated, etc.

    What are 4 types of polymers?

    Synthetic polymers are human-made polymers. They can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers.

    What are the four types of polymers?

    Biomolecules. There are four basic kinds of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids. These polymers are composed of different monomers and serve different functions.

    What is polymer classification?

    The most common way of classifying polymers is to separate them into three groups – thermoplastics, thermosets, and elastomers. The thermoplastics can be divided into two types – those that are crystalline and those that are amorphous.

    What are the 2 types of polymers?

    There are two types of polymers: synthetic and natural. Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted.

    What are the 2 kinds of polymer?

    Polymers are of two types: naturally occurring and synthetic or man made.

    What is classification of polymer?

    What is a polymer?

    Even the DNA in your cells is a polymer. By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for “many parts.”. Each of those parts is scientists call a monomer (which in Greek means “one part”). Think of a polymer as a chain, with each

    How many atoms are in a polymer?

    Regardless of their shape, the molecules are very big. They are so big, in fact, that scientists classify them as macromolecules. Polymer chains can include hundreds of thousands of atoms — even millions. The longer a polymer chain, the heavier it will be higher.

    When does this substance meet the definition of a polymer molecule?

    This chemical meets the definition of a polymer molecule whenever n≥3. This substance consists of 100% polymer molecules (n≥3) and therefore meets criterion 2. However, it does not meet criterion 1 as the substance is not distributed over a range of molecular weights.

    How many amino acids are used to build polymers?

    Although scientists have discovered some 500 different amino acids, animals and plants use only 20 of them to construct their proteins. In the lab, chemists have many options as they design and construct polymers. Chemists may build artificial polymers from natural ingredients.
