Synthesis and properties of ethylene, isoprene and ethylene, isoprene, styrene block polymers

A new method is described to introduce pure blocks of ethylene, isoprene, and styrene into polymer systems composed of these moieties. This method involves the selective catalytic hydrogenation of 1,4‐butadieine‐1,4‐isoprene and 1,4‐butadieine‐1,4‐isoprene‐styrene co and terpolymers to form ethylene...

Description
Summary:A new method is described to introduce pure blocks of ethylene, isoprene, and styrene into polymer systems composed of these moieties. This method involves the selective catalytic hydrogenation of 1,4‐butadieine‐1,4‐isoprene and 1,4‐butadieine‐1,4‐isoprene‐styrene co and terpolymers to form ethylene‐1,4‐isoprene and ethylene‐1,4‐isoprene‐styrene co and trepolymers. The properties of these polymer systems are discussed as a function of composition and degree of polymerization. A useful feature of this technique is the preparation of ABA type thermoplastic elastomers. Eine neue Methode zur Herstellung von Blockpolyrneren aus Äthylen‐, Isopren‐und Styrolblöken wird beschrieben. Durch selektive katalytische Hydrierung werden 1,4‐Butadien‐1,4‐Isopren‐Copolymere und 1,4‐Butadien‐1,4‐Isopren‐Styrol‐Terpolymere zu Äthylen‐1,4‐Isopren‐Copolymeren und Äthylen‐1,4‐Isopren‐Styrol‐Terpolymeren umgesetzt. Die Eigenschaften dieser Polymeren werden in Abhängigkeit von der Zusammensetzung und. vom Polymerisationsgrad diskutiert. In praktischer Hinsicht ist die Herstellung von ABA‐Blockpolymeren als thermoplastische Elastomere von Bedeutung.
