Reactions designed to produce these molecules can exhibit a dangerous thermal runaway in autoacceleration. Titanium or aluminum-based catalysts for making these molecules can control whether they are isotactic (“eye-so-tactic”), syndiotactic (10[1])(“sin-dee-oh-tactic”), or atactic (“ay-tactic”). These molecules have their dispersity index measured with dynamic light scattering. These molecules are the targeted product of reactions that contain initiation, propagation, and termination steps, (10[4])and proceed in a “chain-growth” manner. Common examples of these molecules used in clothing include Teflon and nylon. (10[2]-5[2])For 10 points, name these (-5[1])macromolecules that consist of many repeating monomers. (10[2])■END■ (0[1])
