Q: What is a polymer?
A: A polymer is a large molecule composed of many repeating smaller units called monomers.
Q: What are the two main categories of polymers?
A: Natural polymers and synthetic polymers.
Q: What is a common natural polymer?
A: Cellulose.
Q: What is a common synthetic polymer?
A: Polyethylene.
Q: What is the process of forming polymers from monomers called?
A: Polymerization.
Q: What are the two primary types of polymerization?
A: Addition (chain-growth) polymerization and condensation (step-growth) polymerization.
Q: What is the term for the number of monomer units in a polymer chain?
A: Degree of polymerization.
Q: What is the difference between a homopolymer and a copolymer?
A: A homopolymer consists of a single type of monomer, while a copolymer consists of two or more different types of monomers.
Q: What is a thermoplastic polymer?
A: A thermoplastic polymer is a polymer that can be melted and reprocessed multiple times without significant degradation.
Q: What is a thermosetting polymer?
A: A thermosetting polymer is a polymer that, once cured or hardened, cannot be re-melted or reprocessed.
Q: What is a common thermoplastic polymer?
A: Polypropylene (PP).
Q: What is a common thermosetting polymer?
A: Epoxy resin.
Q: What is a cross-linked polymer?
A: A polymer with covalent bonds connecting the polymer chains, resulting in a network structure.
Q: What is a common example of a cross-linked polymer?
A: Vulcanized rubber.
Q: What is a polymer’s glass transition temperature (Tg)?
A: The temperature at which a polymer transitions from a glassy, rigid state to a rubbery, more flexible state.
Q: What is a polymer’s melting temperature (Tm)?
A: The temperature at which a crystalline or semi-crystalline polymer transitions from a solid state to a molten, liquid state.
Q: What is a branched polymer?
A: A polymer with side chains extending from the main polymer backbone.
Q: What is a linear polymer?
A: A polymer with a single, unbranched chain of monomers.
