Preparation methods and thermal preconditions of formation of the β-modification of isotactic polypropylene (β-IPP) are rewieved. The existence of theoretical upper and lower limit temperature (T(βα) and T(αβ) respectively) of β-IPP formation is demonstrated. Essential characteristics of crystallization, melting and recrystallization of β-IPP are also summarized. In this respect, the attention is called to some new and peculiar phenomena, including the βα- and αβ-bifurcation of growth on the growing crystal fronts as well as the melting and annealing memory effects. Filled systems (composites) and polymer blends based on β-IPP are also covered. An interpretation to polymorphism of IPP is attempted on the basis of enantiotropy.
