Final answer:
In chemistry, solvents are substances that are used to dissolve or disperse other substances. They are commonly used in the production of plastics and synthetic fibers to dissolve and process raw materials.
Step-by-step explanation:
In chemistry, the substance used as a solvent for a number of plastics and synthetic fibers is called a solvent. Solvents are substances that can dissolve or disperse other substances. They are commonly used in various industries, including plastics and synthetic fibers, to dissolve and process raw materials.
For example, acetone is a common solvent used in the production of plastics and synthetic fibers. It is used to dissolve and process the starting materials for these materials, such as resins and varnishes. Acetone is also used as a solvent for vulcanizing rubber.
Other solvents used in the synthesis and processing of plastics and synthetic fibers include toluene, xylene, and chloroform. These solvents help dissolve and process the raw materials, allowing for the production of various plastic and synthetic fiber products.
