epoxy resin
a resin that is formed by mixing a low-molecular-weight prepolymer with a
compound that forms a cross-linked polymer.
graft copolymer
a copolymer that contains branches of a polymer of one monomer grafted onto the
backbone of a polymer made from another monomer.
head-to-tail addition
the head of one molecule is added to the tail of another molecule.
homopolymer
a polymer that contains only one kind of monomer.
isotactic polymer
a polymer in which all the substituents are on the same side of the extended
carbon chain.
living polymer
a nonterminated chain-growth polymer that remains active. Therefore, the
polymerization reaction can continue upon addition of more monomer.
materials science
the science of creating new materials that have practical applications.
monomer
a repeating unit in a polymer.
oriented polymer
a polymer obtained by stretching polymer chains and putting them back together
in a parallel fashion.
plasticizer
an organic molecule that dissolves in a polymer and allows the polymer chains to
slide by each other.
polyamide
a polymer in which monomers are connected by amide groups.
polycarbonate
a polymer in which the monomers are connected by carbonate groups.
polyester
a polymer in which monomers are connected by ester groups.
polymer
a large molecule made by linking monomers together.
polymer chemistry
the field of chemistry that deals with synthetic polymers; part of the larger
discipline known as materials science.
polymerization
the process of linking up monomers to form a polymer.
polyurethane
a polymer in which monomers are connected by urethane groups.
propagating site
the reactive end of a chain-growth polymer.
radical polymerization
a chain-growth polymerization where the initiator is a radical and the propagation
site is a radical.
random copolymer
a copolymer with a random distribution of monomers.
ring-opening
a chain-growth polymerization that involves opening the ring of the monomer.
