Final answer:
A copolymer is a polymer made from two or more different types of monomers. It is created through addition or condensation polymerization reactions and is used to combine various monomer properties to achieve desired material characteristics. The correct option is b.
Step-by-step explanation:
A copolymer is a type of polymer that is formed from two or more different types of monomers. Unlike a polymer made from a single type of monomer, a copolymer combines these various monomers in a repeating pattern through covalent bonds.
This process of forming the copolymer is a result of addition or condensation polymerization reactions. An example of a condensation reaction is the formation of an amide bond, where each time an amide bond is formed, a small molecule like water is released.
Copolymers are used in a wide variety of applications due to their ability to combine different monomer properties to achieve specific characteristics.
It is important to recognize that not all polymers are copolymers; there are also homopolymers, which are made from a single type of monomer.
The formation of copolymers can result in materials with diverse properties, which can be tailored for specific uses. For instance, copolymers play a crucial role in creating different plastics with varying degrees of hardness, flexibility, and durability.
In summary, the correct answer is b. A polymer made from two or more different types of monomers. Polymers, including copolymers, can be either synthetic or natural, and they have a vast range of applications, from plastics to biological substances like DNA and proteins. Option b. is the correct one.
