a type of polymer chain configuration wherein all side groups are positioned on the same side of the chain molecule.

a type of polymer structure in which groups of atoms that are not part of the backbone structure are located either all above or all below the atoms in the backbone chain, when the latter are arranged all in one plane.

Pertaining to a type of polymeric molecular structure containing a sequence of regularly spaced asymmetric atoms arranged in like configurations in a polymer chain.

Isotactic polymers refer to those polymers formed by branched monomers that have the characteristic of having all the branch groups on the same side of the polymeric chain. The monomers are all oriented in the same way: If we represent a monomer by AB then an isotactic polymer is AB-AB-AB-AB-AB-etc.
