Definition: The process of creating large molecules made up of repeating units, known as polymers.

Example: Polymerism is essential in the production of many synthetic materials.

Definition: A process in chemistry where small molecules called monomers join together to form a larger molecule known as a polymer.

Example: The polymerization of the monomers resulted in a strong and flexible material.

Definition: To cause a substance to undergo a chemical process that combines small molecules into a larger, more complex structure.

Example: The scientist decided to polymerize the liquid to create a stronger material.

Definition: Relating to a process in which small molecules combine to form a larger, more complex structure.

Example: The polymerizing agent is essential for creating strong materials.

Definition: To undergo a chemical process where small molecules combine to form a larger, more complex structure.

Example: The scientists are polymerizing the materials to create a new type of plastic.

Definition: A type of organism or substance that can exist in different forms or structures.

Example: The scientist studied a polymorph of the mineral to understand its properties better.

Definition: A type of antibiotic that comes from a soil bacterium and is used to treat infections caused by certain harmful bacteria.

Example: The doctor prescribed polymyxin to treat the patient's severe infection.

Definition: A medical condition that involves inflammation of multiple peripheral nerves at the same time, often leading to pain, weakness, or numbness in the affected areas.

Example: The patient was diagnosed with polyneuritis after experiencing weakness in both legs and hands.

Definition: Describing something that has more than one nucleus, often used in chemistry to refer to compounds with multiple cyclic structures.

Example: The polynuclear compound exhibited unique chemical properties due to its multiple nuclei.

Definition: A large molecule made up of many smaller units called nucleotides, which are the building blocks of DNA and RNA.

Example: Polynucleotides play a crucial role in genetic information storage and transfer.

Definition: A type of plastic made from the polymerization of olefins, commonly used in packaging and other products.

Example: Polyolefin materials are widely used in the production of plastic bags and containers.
