Polymer Chemistry Quiz

A thermosetting polymer known as Bakelite.

A monomer containing a single bond; it's a key component of PVC.

Epichlorohydrin and bisphenol are the building blocks.

Epoxy resin is a strong, durable adhesive that hardens permanently.

Thinners reduce the thickness (viscosity) of paint.

Polymers found in nature, such as starch and proteins.

Thermoplastics have a linear structure, allowing them to be repeatedly softened and reshaped by heat.

Formaldehyde is used in the production of epoxy resin.

Vinyl chloride is the monomer used to make polyvinyl chloride (PVC).

Epoxy resins are commonly used as adhesives in the aircraft industry due to their strength and durability.

A mixture primarily composed of resin and thinner.

A polymer that softens when heated and can be reshaped repeatedly.

Epoxy resin is a common name and has no distinct commercial name, unlike ethyl alcohol or ammonium chloride.

A polymer that can be melted down and reused to make new products.

The degree of tackiness, bonding speed, and durability are key properties of paints, varnishes, and similar materials.

A type of polymer that can be repeatedly softened by heat and reshaped, often formed through addition or condensation polymerization.

A substance added to polymers to prevent the formation of a hard, unworkable skin on the surface.

Cork is the most efficient natural thermal insulator due to its low thermal conductivity.

Cork, surprisingly, is a poor thermal insulator when compared to other materials.

Acrylonitrile Butadiene Styrene (ABS) is used in various applications due to its chemical resistance, such as tank linings, safety helmets and motorcycle mudguards.

Handles of saucepans are made of materials that conduct heat well, allowing you to hold them without the heat transferring too quickly to your hand.

Adhesives are substances used to bind different materials together, creating a strong bond between them.

Heat conductors are materials that allow heat to pass through them easily. Examples include aluminum, paper, and cloth.

When moisture is present, the insulating ability of a material decreases because moisture can conduct heat more effectively than air.

Adhesives used for sealing in the food industry include cellulose derivatives, epoxy resins, silicone resins, and poly vinyls.

Glass wool is a highly effective insulator due to its porous structure. The air pockets trapped within the fibers prevent heat transfer efficiently.

Polymers are categorized based on their response to heat into thermoplastics and thermosetting polymers. Thermoplastics can be repeatedly softened and reshaped by heat, while thermosetting polymers harden permanently after initial heating.

The thermal conductivity of glass wool can vary depending on factors like its composition, density, and porosity. A denser and more porous structure generally leads to better insulation.

Polymers, due to their long chain-like structures, generally have the highest molecular mass compared to other types of molecules.

Thermosetting plastics exhibit strong cross-linking in their molecular structure, leading to their permanent hardened state after initial heating.

A substance that makes up paint. Examples include pigments, binders, and solvents.

Pigments provide color and opacity to paint, making surfaces visible and hiding underlying layers.

A pigment that creates a white color. An example is chromium oxide.

A lubricant used in applications with moving parts that require smooth and friction-free movement. Examples include sewing machines.

Epoxy resins are created through a chemical reaction called addition polymerization, where monomers join together to form long chains.
