Patent ID: 11319389

Abstract:
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 g/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.
