The molecular‐weight distributions of several conjugated soybean vinyl ether homopolymers were studied by means of the integral fractionation technique. Polymers having number average molecular weights of 2,200, 4,800 and 10,000 prepared with stannic chloride as catalyst as well as a polymer having a molecular weight of 3,400 prepared with boron trifluoride as catalyst were included in the study. The observed distributions for all the polymers were found to approximate the socalled “most probable” distributions expected theoretically for polymers obtained by simple difunctional polymerization.
