isotactic macromolecule
A
tactic macromolecule
, essentially comprising only one species of
configurational base unit
, which has
chiral
or prochiral atoms in the
main chain
in a unique arrangement with respect to its adjacent
constitutional units
.
Notes:
In an isotactic macromolecule, the
configurational repeating unit
is identical with the configurational base unit.
An isotactic macromolecule consists of
meso diads
.
