polycondensation

A polymerization in which the growth of polymer chains proceeds by condensation reactions between molecules of all degrees of polymerization.
Notes:
  1. The growth steps are expressed by:
    P x + P y → P x + y + L { x } ∈ { 1 , 2 , ... ∞ } ; { y } ∈ { 1 , 2 , ... ∞ }
    where P x and P y denote chains of degree of polymerization x and y, respectively, and L a low-molar-mass by-product.
  2. The earlier term 'polycondensation' was synonymous with 'condensation polymerization'. It should be noted that the current definitions of polycondensation and condensative chain polymerization were both embraced by the earlier term 'polycondensation'.
