Recycling process for elastomer toughened thermoplastic polymers

A toughened thermoplastic polymer having elastomeric domains in a thermoplastic polymer may be recycled by dissolving the thermoplastic polymer in a solvent to form a solution, wherein the elastomer is dispersed within the solution in the form of elastomeric particulates or droplets; applying a sufficient centrifugal force to the solution to separate the elastomeric particulate matter or droplet from the solution to form a separated system; and (c) recovering the thermoplastic polymer and the elastomeric polymer by removing one or both of the thermoplastic polymer and the elastomeric polymer from the separated system. The recovered elastomer and thermoplastic polymer can then be reused in the same type, similar or different plastics, avoiding degradation that would otherwise occur when recycling the toughened thermoplastic polymer. 可以通过以下方法使在热塑性聚合物中具有弹性体域的经增韧热塑性聚合物再循环：将热塑性聚合物溶解于溶剂中以形成溶液，其中弹性体以弹性体颗粒物或液滴的形式分散于该溶液内；将足够的离心力施加于该溶液中，以将该弹性体颗粒物或液滴与该溶液分离，以形成经分离的体系；以及(c)通过从该经分离的体系中除去该热塑性聚合物和弹性体聚合物中的一者或两者来回收该热塑性聚合物和该弹性体
