Publication number: 20230391977Abstract: Toughened thermoplastic polymers having elastomeric domains in thermoplastic polymer may be recycled by a method comprising dissolving the thermoplastic polymer in a solvent to form a solution, wherein the elastomer is dispersed within the solution as elastomer particulates or droplets, applying a sufficient centrifugal force to the solution to separate the elastomeric particulates or droplets from the solution to form a separated system and (c) recovering the thermoplastic polymer and elastomeric polymer by removing one or both from the separated system. The recovered elastomer and thermoplastic polymer may then be reused in the same type, similar or differing plastics avoiding degradation typically found when recycling toughened thermoplastic polymers.Type: ApplicationFiled: December 10, 2021Publication date: December 7, 2023Inventors: Abidin Balan, Gilbert Bouquet, Elroy Eekman, Pascal Lakeman
