This term refers to the number of repeating units in the polymer molecule. We shall use the abbreviation DP for the degree of polymerization defined in this way. The subscript n used on the parentheses in the foregoing structural formulas for polymers, represent this DP. The relation between degree of polymerization and molecular weight M of the same macromolecule is... 

When the degree of polymerization, defined by n in the above structure, is large, the bisphenol A epoxide is solid and is used as a polymer in its own... 

The onset of the collapse transition (which corresponds, e.g., to vanishing second virial coefScient of interactions between the stars) is shifted with respect to that for linear polymer of the same degree of polymerization (defined by eqn [54]) toward poor solvent strength conditions. This shift is explained by larger intramolecular concentration in the star polymer close to the 6 point, r=0. 

As we have seen, mean field theory predicts that the phase behavior of conformationaly symmetric diblocks can be described in terms of just two quantities, /Ac and/A. A general result of the NSCFT is that, as long as each microphase can be described by a single independent lattice parameter, then the entire microphase diagram of a system of diblock copolymers depends on three parameters, which are / Aeff, the compositional asymmetry /a, and the conformational asymmetry e. Aeff is an effective degree of polymerization, defined by...

Note 2 The terms polycondensation and condensation polymerization , defined previously [6], were synonymous. It should be noted that the current definitions of polycondensation and condensative chain polymerization (see Note 3 under chain polymerization) were both embraced by the previous term polycondensation .
