full_question: In solid-state dye lasers, the gain medium is one of these molecules called PMMA. Partially miscible solutions containing these compounds exhibit a UCST and LCST phase transition. The “electroluminescent conducting” type of these compounds are used in OLED displays. The (*) Flory-Huggins model describes them, and Ziegler-Natta catalysts aid the formation of these molecules. Thermoplastic ones are remoldable and their synthesis can be categorized as step-growth or chain-growth. For 10 points, name these compounds made of repeating units called monomers.
