摘要： 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.

摘要： Disclosed are compositions comprising a) one or more cyclic (meth)acrylate esters; b) one or more alkyl (meth)acrylates; and c) one or more of i to iv; i) the one or more alkyl (meth)acrylates have two or more carbons in the alkyl group; ii) the one or more alkyl (meth)acrylates contain one or more alkyl methacrylates and one or more C2-8 alkyl acrylates; iii) one or more unsaturated compounds containing nucleophilic groups or electrophilic groups; iv) one or more impact modifiers, colorants, mold release agents, flow modifiers, UV absorbers, light stabilizers, fillers, fibers, anti-oxidants, and heat stabilizers. Disclosed are copolymers prepared therefrom having a weight average molecular weight of about 50,000 g/mole or greater and a glass transition temperature of about 100° C. or greater. Disclosed are methods for preparing such copolymers. Disclosed are articles prepared from the compositions.
