    摘要： Methods for treating post-consumer and/or post-industrial waste containing impact modified polymers of monovinylidene aromatic monomers are disclosed. The methods may include forming a solution comprising a solvent and at least one post-consumer and/or post-industrial waste comprising an impact modified polymer wherein the polymer is based on monovinylidene aromatic monomers and an impact modifier having a specific particle size and morphology; separating and removing undissolved and/or undispersed material in the solution from the solution; and separating and removing the solvent from dissolved and/or dispersed material to recover the impact modified polymer; wherein the solvent dissolves and/or disperses the impact modified polymer, and wherein the recovered impact modified polymer maintains the impact modifier particle size and morphology.

    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 C 2-8 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.

    摘要： Compositions comprising at least one copolymers comprising: a) from 20 to 90 percent by weight of one or more vinylidene substituted aromatic compounds; b) from 10 to 80 percent by weight of one or more cyclic (meth)acrylate esters; c) from 0 to 40 percent by weight of one or more unsaturated nitriles; and, d) from 0 to 60 percent by weight of an alkyl (meth)acrylate; wherein based on the weight of the copolymer and the copolymer has a weight average molecular weight of 120,000 Kg/Mole or greater and a glass transition temperature of 100 °C or greater. Disclosed are articles prepared from the compositions which may be fabricated in any known manner. The copolymers, compositions and articles disclosed contain reduced levels of the one or more free/residual/unreacted monomers, such as unsaturated nitriles; may be transparent or opaque; or have a biobased monomer content of 5 percent by weight or greater.
