Types and Properties of Polymers

This set of flashcards covers key vocabulary terms associated with types of polymers, their properties, and applications, enhancing understanding for exam preparation.

Polymer

Materials made up of many small molecules called monomers linked to form long chains.

Thermosoftening Polymers (Thermoplastics)

Polymers that can be softened by heating, reshaped and are fully recyclable.

Thermosetting Polymers (Thermosets)

Polymers that become hard when heated and cannot be reshaped or remelted.

Addition Polymerization

A process where monomers with double bonds link together without loss of any atoms.

Condensation Polymerization

A process where monomers with two functional groups react to form a polymer while releasing small molecules like water.

ABS (Acrylonitrile Butadiene Styrene)

A thermoplastic known for its strength and durability, commonly used in car dashboards and toys.

Nylon (Polyamide)

A thermoplastic used for bearings and ropes, known for being tough and self-lubricating.

Polycarbonate

A hard, strong thermoplastic used in eyewear lenses and machine parts.

Urea Formaldehyde

A thermosetting polymer used in electrical fittings and known for its strength and insulating properties.

PLA (Polylactic Acid)

A biodegradable polymer derived from corn starch or sugarcane, used for food packaging.

Recyclable Polymers

Polymers that can be melted and reshaped for reuse, reducing environmental waste.

Bio-based Polymers

Polymers made from renewable sources that help reduce dependence on fossil fuels.

Environmental Impact of Polymer Recycling

The process mitigates plastic waste and promotes sustainability through the reuse of materials.

Polypropylene

A tough and flexible thermoplastic commonly used in containers and ropes.

Polyvinyl Chloride (PVC)

A stiff and chemical-resistant thermoplastic used for pipes and cables.

Melamine Formaldehyde

A thermosetting polymer used for making heat-resistant tableware.
