polycondensation

https://doi.org/10.1351/goldbook.P04722
A @P04740@ in which the growth of polymer @C00946@ proceeds by condensation reactions between molecules of all @D01569@.
Notes:
  1. The growth steps are expressed by: \[\text{P}_{x} + \text{P}_{y}\rightarrow \text{P}_{x + y} + L\hspace{35pt} \{x\}\in \{1,2, \dots \infty\}; \{y\}\in \{1,2, \dots \infty \}\] where \(\text{P}_{x}\) and \(\text{P}_{y}\) denote chains of @D01569@ \(x\) and \(y\), respectively, and \(\text{L}\) a low-molar-mass by-product.
  2. The earlier term 'polycondensation' was synonymous with 'condensation @P04740@'. It should be noted that the current definitions of polycondensation and @C00958@ were both embraced by the earlier term 'polycondensation'.
