What are the properties of polymers?
Factors that affect their properties include impact resistance, ductility, elasticity, translucence, reflectivity and brittleness. These traits seen in polymers are due to the type of polymerization reaction, such as addition or condensation reactions and how the process is specifically carried out, e.g. altering temperature and pressure (Johnson, 2019). Polymer chains that are tightly twisted result in a stronger physical structure than monomers that are loosely bonded which are more likely to possess flexible and stretchy properties (Johnson, 2019).
What is the difference between a condensation reaction and a polymerization reaction?
Condensation reaction. Condensation polymerization reactions are different in that instead of double bonds, these monomers have at least two functional groups (alcohol, amine, or carboxylic acid) and these form a linkage chain reaction (Kotz and Treichel, 2019).

Why is polypropylene important?
Polypropylene is everywhere because it can take on yet another key form: fibers. It’s extremely valuable to the clothing, fashion, and sports industries because it’s so resilient—it resists wear and tear, the sun, mold, bacteria, and water. It’s idea for activewear for outdoor sports, as well as equipment and accessories. These fibers can keep you warm as a base layer in the winter, and cool in the summer with moisture-wicking abilities. You can even personalize this kind of polypropylene, which is what makes it such a popular choice for promotional tote bags.

What is PET used for?
Polyethylene terephthalate (PET) is a strong, lightweight, transparent plastic. When PET is used to make fabric, it’s known as polyester. A recent post, Processing Polyethylene, discussed this widely used plastic that has applications in packaging, consumer goods, and coatings. According to The Plastics Industry Trade Association, the use of polyethylene took off after the second world war when a variety of high and low density versions were developed. Large-scale production of these materials reduced their cost dramatically, enabling them to compete with the older plastics and with the more traditional materials such as wood, paper, metal, glass, and leather. Today, both High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) remain among the most commonly-used plastics. Both are strong, non-leaching, and frequently used in food packaging, but HDPE is less flexible than LDPE.

What do students learn about polymeric materials?
They learn how chemical composition affects the physical properties of the materials that they encounter and use frequently, as well as how cross-linking affects the properties of polymeric materials.
How does cross linking affect polymer properties?
Remember, cross-linking affects polymeric material properties by limiting the motion of individual polymer chains within a material (as highlighted visually in Figure 5). We can see the effect of cross-linking on polymeric materials by comparing the strength of polyethylene and cross-linked polyethylene. Polyethylene, as discussed previously, is used to make plastic shopping bags and many plastic containers, whereas cross-linked polyethylene (abbreviated as PEX) tubing is used in plumbing applications. The strengths of a polyethylene plastic bag and a water pipe made from cross-linked polyethylene are very different. Cross-linking of the polymer chains strengthens the material properties present in PEX tuning.
