Abstract
Procedure for regulating the molecular weight of macromolecular substances by polymerization of olefins with 2-4 carbon atoms by the Ziegler low pressure process and by introduction of molecular hydrogen, characterized by introducing the hydrogen alternately with an inert gas into the polymerization vessel , in phases fixedly polymerized, and then continue the polymerization with monomer or monomers respectively.
