The surface adsorption sites of titanium chloride films that can be used as model Ziegler-Natta polymerization catalysts Ž . have been investigated with temperature-programmed desorption TPD of various probe molecules. The adsorption sites can be differentiated depending on the heat of desorption of
## Abstract **Summary:** Self‐supported and MgCl~2~‐supported Ziegler‐Natta catalysts, produced by two catalyst synthesis methods are compared. Borealis Polymers OY (Finland), who supplied the catalysts, developed the catalyst synthesis methods. The first method (Method One) is based on an emulsion
