The three structural forms of poly(alkenes) edit
Isotactic edit
Isotactic polymers have all their R-groups pointing in the same direction.
Syndiotactic edit
Syndiotactic polymers have their R-groups pointing in alternating directions.
Atactic edit
Atactic polymers have no regularity in the direction of their R-groups.
