Task: Text Categorization
Input (English): When in solutions of these substances, colloid particles can be pushed together by an osmotic imbalance known as the depletion interaction, and in low concentrations these substances can cause bridging flocculation. When in a theta solvent, these substances follow a random flight model. More generally, their interactions in solution are modeled by Flory-Huggins theory. These substances can be synthesized with the help of Ziegler-Natta catalysts. For 10 points, name these large molecules such as Kevlar and nylon which are made up of many repeating monomers.
Output (English): Science
