Auto-acceleration effect is one of the important characteristics of radical polymerization macrokinetics
which have great influence on polymerization progress and the synthesized product. The content of auto-acceleration effect is an emphasis and difficulty in the teaching and learning of radical polymerization kinetics. In order to help students understand the related content of auto-acceleration
the experimental phenomena
cause
results generated and influencing factors of auto-acceleration as well as the difference between auto-acceleration effect and the gelation of three dimensional polycondensation were summarized in this paper with reference to relevant polymer chemistry textbooks.
