A new class of polymer (nanocomposite) materials of di‐ and triblock polymers of polystyrene, poly(butyl acrylate) and poly(acetoacetoxyethyl methacrylate) with a core‐shell particle morphology and a controlled molecular weight distribution were prepared via emulsion polymerization in the presence of a reversible addition/fragmentation chain transfer agent. The film properties of these blocks are far superior to the conventional blend of the two polymers even after crosslinking with 1,6‐hexadiamine.
