Group transfer polymerization (GTP) a of acrylic monomers is mediated by a trialkylsilyl‐capped growing chain end. It operates at room temperature and above and permits a high degree of molecular architecture control. Block, comb, graft, star, and loop polymers are readily synthesized. It appears that GTP is an associative process under mild nucleophilic catalysis and a dissociative process under strong nucleophilic catalysis.
