|---|---|
 Acrylic polymers | Class of polymers produced from a variety of organic compounds, such as methyl methacrylate, ethyl methacrylate, and acrylic acid. |
| Addition polymerization | Free radical polymerization that produces no byproducts. |
| Copolymers | A polymer that consists of two or more types of mers or units. |
| Cross-linking | Strands of the polymer network are linked together. |
| Degree of conversion | The extent to which all monomer is polymerized. |
| Degree of polymerization | The extent to which monomer is converted into polymer. |
| Denture bases | Material used to contact the oral tissues and support artificial teeth. |
| Fillers | Particulates added to polymers to change optical or physical properties of polymers. |
| Free-radical polymerization | Uses monomers that have an unsaturated carbon-carbon double bond as their reactive group. |
| Homopolymers | One type of monomer unit. |
| Initiator | Reactive material that starts a chemical reaction. |
| Monomers | A single organic molecule used to prepare a high-molecular weight polymer. |
| Plasticizer | Compound added to a polymer to reduce its hardness. |
| Polymer | Organic molecules of high molecular weight made up of many repeating units. |
| Polymerization | Process of preparing large molecules from small ones. |
| Residual stress | Stress that remains in a material as a result of manipulation; when released by the action of time and temperature, distortion of the material results. |
