摘要：
The kinetic parameters of the synthesis of iso-, syndio-, hemiisotactic, and stereoblock PP in a liquid propylene using a series of ansa-metallocenes with C-1, C-2, and C-s symmetries activated by methylaluminoxane were studied. For several metallocenes, the effect of hydrogen on the activity and molecular mass characteristics of PP was assessed. The microstructure of the polymer chains, as well as the molecular mass characteristics and thermal, mechanical, and optical properties of the produced polymers, were investigated.
