What Is The End Group Analysis? End group analysis is the most important absolute method of obtaining number-average molar mass values for polymers of the step-growth polymerization type. It is shown that large differences may arise between the value determined by titration and the actual amino end group content. How end groups of polymer affects
What Does The Degree Of Polymerization Tell Us? 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. Number average DP and weight average DP are the two
How Does Degree Of Polymerization Affect The Melting Point? In general, increasing degree of polymerization correlates with higher melting temperature and higher mechanical strength. What affects melting point of polymers? The polymer melting point Tm is increased if the double bonds, aromatic groups, bulky or large side groups are present in the polymer chain, because
In Which Step Of PCR Taq Polymerase Is Used? “Which of the following steps are catalysed by Taq polymerase in a PCR reaction ?” The final step of PCR is extension, wherein Taq DNA polymerase (isolated from a thermophilic bacterium Thermus aquaticus) synthesises the DNA region between the primers, using dNTPs (denoxynucleoside triphosphates) and Mg2+.
How Do You Calculate The Length Of A Polymer Chain? To get the chain contour length How do you calculate polymers? Divide the molecular weight of the polymer by the molecular weight of the monomer unit to calculate the degree of polymerization. If the molecular mass of tetrafluoroethylene is 120,000, its degree of polymerization is
How Does Molecular Weight Affect Polymer Properties? The lower the molecular weight, lower the transition temperature, viscosity, and the mechanical properties. Due to increased entanglement of chains with increased molecular weight, the polymer gets higher viscosity in molten state, which makes the processing of polymer difficult. Why is the molecular weight of a polymer so
