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 (“sin-dee-oh-tactic”), or atactic (“ay-tactic”). These molecules have their dispersity (10[1])index measured with dynamic light scattering. These molecules are the targeted product of reactions that contain initiation, (10[1])propagation, (-5[1])and termination (10[1]-5[2])steps, and proceed in a “chain-growth” manner. (-5[1])Common examples of these molecules used in clothing include Teflon and nylon. For 10 points, (10[1])name these macromolecules that consist of many repeating monomers. ■END■ (10[2]0[3])
