Glossary: Polymer chemistry
- 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.
- 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.
- 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.
- A large molecule made by linking smaller molecules ("monomers") together.
- A process that links smaller molecules together to form a larger molecule.
- 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.
