Study Notes
Polymerization
- Polymerization is a process in which small molecules (monomers) react to form a large molecule (polymer)
Types of Polymers
- Based on the monomer unit, there are two types of polymers: homopolymers and copolymers
- Homopolymers: composed of a single type of monomer unit
- Copolymers: composed of two or more different monomer units
Homopolymer Example
- Polyethylene is an example of a homopolymer, composed of only ethylene monomers
Copolymers
- Copolymers are composed of two or more different monomer units
- There are four basic structures of copolymers: random, alternating, block, and graft
Copolymer Structures
- Random copolymers: monomer units are randomly distributed along the polymer chain
- Alternating copolymers: monomer units alternate along the polymer chain
- Block copolymers: monomer units are grouped together in blocks along the polymer chain
- Graft copolymers: one polymer chain is grafted onto another polymer chain
Graft Copolymer Creation
- Graft copolymers are created by chemically bonding a side chain (branch) to a main polymer chain
Thermoplastics
- Thermoplastics are characterized by their ability to be melted and reformed without undergoing any significant chemical change
