A novel method is used to study topological and molecular structure of different kinds of sulfur (mineral and two polymeric types). It is based on thermomechanical analysis of solid (not dissolved) polymer. It was found that a deep difference in their molecular weight distributions and in their crystallinity degrees exist. Both mineral and polymeric sulfur have polymer nature. © 1997 John Wiley & Sons, Inc. J Appl Polm Sci 65:499–505, 1997
