Resumen:
We identify the main approximations underlying several methods that have been used to model stepwise, irreversible copolymerizations with intramolecular reaction allowed, and we study their ranges of validity. In order to do this, all approximations are applied to the linear A2 + B2 system, for which comparison against an exact solution is possible. We also combine approximations found in different models to give "hybrid" models. We have found that for this linear system some approximations never give good results, others may be used when ring formation is low, and the better ones may be applied with low to moderate levels of intramolecular reaction. None of them is satisfactory when ring formation is very high.
