- 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 P_x and P_y denote chains of @D01569@ x and y, respectively, and L a low-molar-mass by-product.
- 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'.
