23. The molecular weight of a particular polymer molecule is a product of the degree of polymerization and the molecular weight of the repeating unit. Number of monomer molecules which take part in polymerization is (1 Point) Degree of polymerization Molecular weight of polymer Tg of polymer None of the above DP No ' N Thus, the degree of polymerization can be expressed by DP = No N0d-P) i 1-P Consider a reaction that can be pushed to 90% completion. In step-growth polymerization, the Carothers equation (or Carothers' equation) gives the degree of polymerization, X n, for a given fractional monomer conversion, p.. A common means of expressing the length of a chain is the degree of polymerization, which quantifies the number of monomers incorporated into the chain. New insulating paper has typically a DP of 1100 and a high tensile strength. 1.2 The degree of polymerization (or the degree of condensation) of a particular cellulose molecule is the number of anhydro-Î²-glucose monomers, C 6 H 10 O 5, in the cellulose molecule. For most industrial purposes, degrees of polymerization in the thousands or tens of thousands are desired. The extent of paper degradation is represented by the degree of polymerisation or DP of paper. There are several versions of this equation, proposed by Wallace Carothers, who invented nylon in 1935. Information and translations of degree of polymerization in the most comprehensive dictionary definitions resource on the web. What does degree of polymerization mean? Degree of polymerisation of paper.   For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by. Meaning of degree of polymerization. Degree of Polymerization There are several ways to define the degree of polymerization for a block copolymer. The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule.. For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by â¡ =, where M n is the number-average molecular weight and M 0 is the molecular weight of the monomer unit. Degree of polymerization (DP) is one of the most important structural properties of cellulose. Definition of degree of polymerization in the Definitions.net dictionary. The degree of polymerization, DP is the original number of molecules divided by the remaining number of molecules and approaches a number equal to the original number of molecules as N approaches one. The degree of polymerization, or DP, is usually defined as the number of monomeric units in a macromolecule or polymer or oligomer molecule. Cellulose chain length expressed as cellulose DP can affect the mechanical properties of composite materials and paper products, the solubility of cellulose in a given solvent, and the efficiency of enzymatic hydrolysis of lignocellulosic biomass. The degree of polymerization (\(DP\)) in a polymer molecule is the number, n, of repeating units in the polymer chain. In linear polymers the individual polymer chains rarely have exactly the same degree of polymerization and molar mass, and there is always a distribution around an average value. The most naive one is just the total number of monomers: N1 = NS + NB A more sophisticated way is to use the geometric mean of NS and NB: N2 = 2 sqrt{NS NB} This corresponds to introducing a mean molar volume v = sqrt{vS vB}
