Polymerism

Definitions

  • Webster's Revised Unabridged Dictionary
    • n Polymerism (Chem) The state, quality, or relation of two or more polymeric substances.

Century Dictionary and Cyclopedia
    • n polymerism In chem., that property of certain compounds by virtue of which they differ in their molecular weights and in their chemical properties, though formed from the same elements, combined in the same proportion. Thus, the molecular weights of butyric acid (C4H8O2) and aldehyde (C2H4O) are 88 and 44 respectively and their chemical properties are wholly unlike, but both contain the same elements—carbon, hydrogen, and oxygen—combined in the same proportion. See isomerism, metamerism.
    • n polymerism Multiplicity of parts; presence of many parts in one whole.

    • n Polymerism pō-lim′ėr-ism a particular form of isomerism, the property possessed by several compounds of having similar percentage composition but different molecular weights.

Indeed, the number (nM DS bg ) of relaxation steps between growth steps can be view as a relaxation process for chains during the polymerization stage.
Polymer chain generation for coarse-grained models using radical-like polymerization
Thus, in this Rouse-like regime, topological constraints do not play a significant role and one may expect that chains with average length hN (t)i < Ne ∼ N/3 dominate the polymerization, following a Rouse-like chain dynamics.
Polymer chain generation for coarse-grained models using radical-like polymerization
Chains with mean size hN (t)i > Ne ∼ N/3 follow this reptation-like dynamics, and the polymerization process is slowed down.
