  • Patent number: 11034822
    Abstract: The embodiments of the invention relate to recycled rubber masterbatch which exhibits a sufficient level of green strength and tack. The devulcanization of thermoset rubber is provided by reactive mixing of pulverized rubber, thermoplastic matrix, main-chain backbone antidegradant and green strength enhancer in the presence of a devulcanizing promoter. The embodiments of the invention also provide a thermoplastic dynamically post-vulcanized rubber which comprises at least one devulcanized rubber masterbatch and a polymer, wherein the rubber component is dispersed as a domain in a continuous resin phase and is selectively crosslinked during melt mixing with a molten thermoplastic.
    Type: Grant
