It is shown that in a series of precipitated iron catalysts, some show a break in the Anderson‐Schulz‐Flory (ASF) plot of the distribution of linear products and others do not. It is also shown that the above break is due solely to the change in slope of the linear paraffins and that no such break occurs in the distributions of α or β‐olefins. Our conclusion is that the paraffins and olefins are all primary products and that each has a characteristic rate of termination, but all have a common rate of propagation. A growth scheme which explains our observations is presented.
