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'.
