What is the average rate of polymerization?
What is average rate of polymerization ? 2000 bp per second.
What is degree of polymerization?
The degree of polymerization (DP or Xn) is defined as the number of monomer units in the polymer. It is calculated as the ratio of molecular weight of a polymer and molecular weight of the repeat unit.
How do you find the degree of polymerization of polystyrene?
The mathematical expression for the required degree of polymerization of the given substance is: Degree of polymerization=MnM Degree of polymerization = M n M , where, Mn is the value of the molecular weight of the given polymer.
How do you calculate average functionality?
Average, which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
Why is degree of polymerization important?
Correlation with physical properties Polymers with identical composition but different molecular weights may exhibit different physical properties. In general, increasing degree of polymerization correlates with higher melting temperature and higher mechanical strength.
How do you control the degree of polymerization?
By using postassembly ligand photo-cross-linking, we established a method to arrest NR polymer growth after a particular self-assembly time, and in this manner, using kinetics of step-growth polymerization, we achieved control over the average degree of polymerization of plasmonic polymers.
What is degree of polymerization example?
The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule. For example, in nylon-6,6, the repeat unit contains the two monomeric units —NH(CH2)6NH— and —OC(CH2)4CO—, so that a chain of 1000 monomeric units corresponds to 500 repeat units.
