The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule. [1] [2] [3]
31 sty 2017 · The degree of polymerization can be calculated by using the following relationship if a molecular weight of a polymer molecule is known. M= (DP) M 0 M is the molecular weight of the polymer, DP is the degree of polymerization and the M 0 is the formula weight of the repeating unit.
12 lip 2023 · Examples of naturally occurring condensation polymers are cellulose, the polypeptide chains of proteins, and poly(β-hydroxybutyric acid), a polyester synthesized in large quantity by certain soil and water bacteria. Formulas for these will be displayed below by clicking on the diagram.
The degree of polymerization can be calculated by dividing the molecular weight of the polymer by the molecular weight of the repeating unit (monomer). Different polymerization techniques can lead to different degrees of polymerization for the same monomer due to variations in reaction conditions.
If a polymerization is performed using a 500:1 ratio of initiators to monomers and the reaction reaches 85% conversion, what is the degree of polymerization? If this chain reached 100% conversion, then the degree of polymerization would be 500. At 85% conversion, DP = 425.
the number of monomers in one polymer molecule, “degree of polymerization” n = 10,000,000 / 71 = 140,850 (mol. wt. of monomer, acrylamide = 71) Physical Types of HMW Polymers Dry Polymer Cationic, anionic, non-ionic Molecular weight: up to 10 M (cationic), up to 20M (anionic, non-ionic) Up to 90% active Polymer particle size: 0.1 -2 mm
12 wrz 2021 · The number of enchained monomers in an average polymer chain in a material is called the degree of polymerization (DP). Notice that key point: it is just an average. In any given material, there will be some chains that have added more monomers and some chains that have added fewer.
