Utility
Recycling Method for Elastomer Toughened Thermoplastic Polymers
7 Dec 23
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.
