  • Process for preparing thermoplastic elastomer compositions and thermoplastic elastomer compositions
    Patent number: 5191005
    Abstract: Thermoplastic elastomer compositions are prepared by feeding a mixture of (a) a peroxide crosslinking type olefin copolymer rubber, (b) a peroxide decomposition type olefin plastics and optionally, (c) a peroxide non-crosslinking type hydrocarbon rubbery substance through a hopper into a cylinder of an extrusion machine, and feeding simultaneously (d) a mineral oil type softener, or both (d) and (e) silicone oil, through an inlet provided on the cylinder separately from the hopper, thereby dynamically heat treating the resulting mixture in the presence of organic peroxide to prepare a partially crosslinked thermoplastic elastomer composition.
