Polymorphism in isotactic polypropylene
WebThe analysis of the potential energy of the crystal lattice of isotactic polypropylene during the βα phase transition was carried out. This transformation was realized by rotations and translations within a collection of 10 iPP helices. The lattice energy was calculated by means of the atom-atom potential method.
