6. Molar distribution in linear polycondensates
The following relationships are valid for the stoichiometric systems AA + BB and for the systems AB + AB, provided that the degrees of polymerization are expressed in A′B′ units.
The product of a polycondensation consists of a mixture of monomer, dimer, trimer, etc. molecules; a chain formed of x A′B ′ units is referred to as x-mother.
6.1 Number fraction of x-mers in the mixture
In the following n x is the number of x-mers and n is the number of all molecules contained in the mixture resulting from polycondensation. n x /n is the number fraction or mole fraction of the x-mers, it is also the probability P x ...
