Abstract
Process for synthetically obtaining a polyisoprene of structure and properties essentially equal to hevea or natural rubber, characterized by preparing a practically cis polyisoprene by polymerizing isoprene in the presence of metallic lithium and in the absence of actual elemental or nascent nitrogen and oxygen, of organic compounds containing oxygen and unsaturated compounds other than isoprene.
