Technology

The Hypol Polymerization process utilizes a High-Activity, High-Stereospecificity Catalyst which was developed jointly by Himont/Montedison and Mitsui. In Second-Generation Hypol II units, a Bulk Loop Reactor is used for the First Stage. Homopolymers and Random Copolymers are made in an Auto-Refrigerated Adiabatic Vessel using the Bulk Polymerization Process. Impact Copolymers are then made in the Second Stage Gas Phase Reactor. Line Configurations with more than Two Reactors have been used in order to Manufacture Polymers with specific Characteristics or Properties.
