Glossary
acetate. (CH3COO-, C2H3O2-) acetate ion.
1. an ion formed by removing the acidic hydrogen of acetic acid*, HC2H3O2. 2. a compound derived by replacing the acidic hydrogen in acetic acid. 3. A fiber made of cellulose* acetate.

copolymer.
A polymer* composed of two or more different monomers*. The different monomers can be linked randomly, or in repeating sequences, or in blocks, or as side chains off the main chain.

ebulliometry. ebulliometric.
Determination of average molecular weight of a dissolved substance from the boiling point elevation* of the solution.

monomer.
A small molecule that is linked with large numbers of other small molecules to form a chain or a network (polymer).

osmometry. Compare with osmosis*.
Determination of the average molecular weight of a dissolved substance from measurements of osmotic pressure*.

polymer.
A large molecule made by linking smaller molecules ("monomers") together.

polymerization.
A process that links smaller molecules together to form a larger molecule.

polymerize.
To link smaller molecules together to form a larger molecule.

thermoplastic. Compare with thermosetting*.
A polymer that softens or melts on heating, and becomes rigid again on cooling. Thermoplastic polymer chains are not cross-linked. Polystyrene is a thermoplastic.

thermosetting. thermosetting plastic. Compare with thermoplastic*.
A polymer that solidifies on heating and cannot be remelted. The setting action results from crosslinking of the polymer chains at high temperature- a process that is not reversed by cooling and reheating.

vinyl. polyethylene.
A polymer* made by linking ethylene (CH2=CH2) or substituted ethylene molecules together.
