A polyacrylate-polycarbonate copolymer comprises a polycarbonate block comprising aromatic carbonate units, and a polyacrylate block derived from a difinctional polyacrylate polymer having the formula <?in-line-formulae description="In-line Formulae" end="lead"?>Z<SUP>1</SUP>-(M)<SUB>x</SUB>-Z<SUP>2 </SUP><?in-line-formulae description="In-line Formulae" end="tail"?> 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 Z<SUP>1 </SUP>and Z<SUP>2 </SUP>are each independently functionalized terminal groups of the formula <?in-line-formulae description="In-line Formulae" end="lead"?>-(A<SUP>3</SUP>)<SUB>y</SUB>-B, <?in-line-formulae description="In-line Formulae" end="tail"?> wherein B is a reactive group comprising a hydroxy or non-hydroxy group, A<SUP>3 </SUP>an aliphatic group, an aromatic group, or an aliphatic-aromatic group, y is 0 or 1, A<SUP>3 </SUP>is free of hydrogen atoms beta to B when B is a hydroxy group, and B and A<SUP>3 </SUP>are each free of sulfur atoms. A method of making, a thermoplastic composition, and articles are also disclosed.
