Polypropylene was first polymerized on March 11 1954 by Giulio Natta.[citation needed] At first it was thought that it would be cheaper than polyethylene.
The Polypropylene, with the CAS registry number 9003-07-0, has the systematic name of prop-1-ene. For being a kind of tan to white odorless solid, it is insoluble in water and could react with chlorine, fuming nitric acid and other strong oxidizing agents. Besides, its product categories are including Polymers; Nanohybrids; Hydrophobic Polymers; Olefins; Propylene.
Physical properties about Polypropylene are: (1)ACD/LogP: 1.83; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.827; (4)ACD/LogD (pH 7.4): 1.827; (5)ACD/BCF (pH 5.5): 14.411; (6)ACD/BCF (pH 7.4): 14.411; (7)ACD/KOC (pH 5.5): 234.973; (8)ACD/KOC (pH 7.4): 234.973; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 0 ; (13)Index of Refraction: 1.348; (14)Molar Refractivity: 15.673 cm3; (15)Molar Volume: 73.149 cm3; (16)Polarizability: 6.213 ×10-24 cm3; (17)Surface Tension: 13.615 dyne/cm; (18)Density: 0.575 g/cm3; (19)Enthalpy of Vaporization: 18.42 kJ/mol; (20)Vapour Pressure: 8476.793 mmHg at 25°C.
Preparation of Polypropylene: Commercial synthesis of syndiotactic polypropylene is carried out with the use of a special class of metallocene catalysts. They employ bridged bis-metallocene complexes of the type bridge-(Cp1)(Cp2)ZrCl2 where the first Cp ligand is the cyclopentadienyl group, the second Cp ligand is the fluorenyl group, and the bridge between the two Cp ligands is -CH2-CH2-, >SiMe2, or >SiPh2. These complexes are converted to polymerization catalysts by activating them with a special organoaluminum cocatalyst, methylaluminoxane (MAO).
Uses of Polypropylene: Polypropylene is widely applied in many fields. It could be used in the industry of textiles, plastic parts and all kinds of containers, and also the lab apparatus; It could also be used in loudspeakers, components for cars and other stationery.
