The topologically self-constrained structures of catenated polymers are of high interest for the study of its unique physical properties. A versatile approach for the synthesis of catenated homo and blockcopolymers was demonstrated via (1) growing the polymer chain from ATRP initiators templated in phenanthroline Cu(I) complex and (2) ring closing of resulting four arm type polymers via intra-molecular atom transfer radical coupling. The formation of the interlocked topology of desired polymers was confirmed by GPC and AFM analysis.
