   | Atactic | Side groups are randomly oriented. | Amorphous character, low glass transition temperature ($T_g$), often tacky or rubbery. |
   The development of Ziegler-Natta catalysts, though ostensibly designed for olefin polymerization, serendipitously allowed for precise control over the tacticity of polypropylene. It is now known that catalyst choice, rather than [temperature](/entries…
