Abstract
A polyacrylate-polycarbonate copolymer comprises a polycarbonate block comprising aromatic carbonate units, and a polyacrylate block derived from a difunctional polyacrylate polymer having the formulaZ1-(M)x-Z2 wherein M is an acrylate block unit comprising a reaction residue of a (meth)acrylate monomer, a non-(meth)acrylate monomer, or a combination comprising a (meth)acrylate and a non-(meth)acrylate monomer, at least one acrylate block unit is a (meth)acrylate monomer; x is greater than one; and Z1 and Z2 are each independently functionalized terminal groups of the formula-(A3)y-B,wherein B is a reactive group comprising a hydroxy or non-hydroxy group, A3 an aliphatic group, an aromatic group, or an aliphatic-aromatic group, y is 0 or 1, A3 is free of hydrogen atoms beta to B when B is a hydroxy group, and B and A3 are each free of sulfur atoms. A method of making, a thermoplastic composition, and articles are also disclosed.
