Laboratory work #7: «Polymers and Their Properties»
Description: In this laboratory work, students investigate the properties of various types of plastics commonly found in everyday life. The experiment includes observing their behavior during heating and burning, determining their density using water and salt solution tests, and checking their solubility in an organic solvent (acetone). The work allows students to see in practice how the structure of a polymer influences its properties and applications.
