Curing theory of the Aai–Bbj type polycondensation. (I) intramolecular cyclization and gelation equations

Abstract: This paper investigates in detail the ring-chain competition in A,,-B,, type polycondensations by use of a molecular model of tree branching and the basic principles of probability. The intramolecular cyclization equations and the critical gelation condition containing both intermolecular and intramolecular reaction parameters have been obtained.

“…If there were no intramolecular reactions, the experiment value of critical extent of reaction ( q exp c ) should be equal to the theoretical value q c . But in real polymer solution, especially in dilute solution, there are some intramolecular reactions besides intermolecular reactions . So the experiment value of critical extent of reaction must be higher than the theoretical one ( q c ).…”

“…But in real polymer solution, especially in dilute solution, there are some intramolecular reactions besides intermolecular reactions. 15 So the experiment value of critical extent of reaction must be higher than the theoretical one (q c ). This fact means that the intramolecular cyclization in our system cannot be ignored.…”
