How do you calculate the degree of polymerization of polypropylene?
Divide the molecular weight of the polymer by the molecular weight of the monomer unit to calculate the degree of polymerization.
How do you find the degree of polymerization?
Divide the molecular mass of the polymer by the molecular weight of the monomer.
For example, if the molecular mass of tetrafluoroethylene is 1,20,000, then its degree of polymerization is calculated as 1,20,000 / 100 = 1,200.
Therefore, the degree of polymerization is 1,200.Ans.
To calculate the degree of polymerization, divide the polymer's molecular weight by the monomer's molecular weight.
If tetrafluoroethylene has a molecular mass of 120,000, its degree of polymerization is 120,000 / 100 = 1,200.
What is the polymerization of polypropylene?
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications.
This polymer is produced via chain-growth polymerization from the monomer propylene.
