Polypropylene
Propylene - Also known as propene, is an unsaturated organic compound. - Chemical formula: C3H6. - Source: Byproducts of oil refining and natural gas processing. During oil refining propene are produced as a result of cracking large hydrocarbons.
Functional group
Properties Physical properties
Chemical properties
- Molecular weight : 42.08 g/mol - Melting point: -301.4F - Boiling point: -53.9F. - colorless gas with a petroleum-like odor. - The vapors are heavier than air. Any leak can either be liquid or vapor.
- Asphyxiation - Highly Flammable - Upper respiratory tract - Irritant, Can cause explosion.
Polypropylene - Chemical formula: (C3H6)n - Origin: Synthetic - Structure: Branched chain polymers - Polymer types: Thermoplastic - Types of monomer: Both copolymers and homo polymer
Structure Homo polymer
Copolymer
Polymerization - Additional polymerization ● Free radical polymerization
