Inorganic Polymers
- Natural inorganic polymers include materials like obsidian, diamond, and quartz, forming a distinct class due to their inorganic nature.
Thermoset Polymers
- Thermoset polymers are characterized by their ability to form irreversible bonds during curing, resulting in a hard, inflexible structure resistant to heat.
Polymer Classification
- Long, unbranched chains of repeating monomer units classify as linear polymers, known for their structured and organized arrangement.
Synthetic Polymers
- The earliest type of synthetic polymer is Bakelite, created as a modification of natural phenolic compounds, marking a significant advancement in materials science.
Polymerization Process
- The fundamental chemical process where monomers are chemically bonded to form larger molecules is known as polymerization.
Homopolymers
- Polymers made of identical monomer units are termed homopolymers, showcasing uniform structure and properties throughout.
Copolymer Structures
- The four basic structures of copolymers include:
- Alternating copolymers
- Block copolymers
- Random copolymers
- Graft copolymers, each allowing varied properties and applications.
Environmental Impact
- The potential environmental impacts of the polymer industry are described by the term "polymer pollution," highlighting concerns over waste and ecological effects.
Distinct Monomer Polymers
- Polymers made from two distinct monomers are referred to as copolymers, enabling the combination of different characteristics from each monomer.
