Thioethers of 2‐methylenepropane‐1,3‐thiol were prepared as a new class of symmetrically substituted chain transfer agents for addition‐fragmentation‐type free radical polymerization of styrene. Ester‐ and hydroxy‐functional thioethers were prepared to introduce two functional end groups during free radical polymerization. Chain transfer constants were measured and compared to those of the corresponding disulfides.
