Abstract Polymer chemistry focuses on synthesis and chemical reaction of polymers, and the philosophical relationship between quantitative and qualitative change runs throughout it. The relationship between quantitative and qualitative change is discussed. The molecular weight, degree of polymerization, condensation and thermal transformation, condensation polymerization, radical polymerization, radical copolymerization, emulsion polymerization are involved, and the typical cases are selected to be analyzed. The philosophical principles of quantitative change and qualitative change are expounds by the leap from quantitative change to qualitative change, the mutual transformation and infiltration of quantitative change and qualitative change, the retroaction of of qualitative change to quantitative change, and the guides of philosophy theory to practice.
