Abstract

New kid on the block: Unprecedented polystyrene-block-poly(methylenephosphine) copolymers are accessible from the reaction of living polystyrene with the phosphaalkene (see scheme; Mes=2,4,6-Me3C6H2). The living anionic polymerization of P[DOUBLE BOND]C bonds represents a new development in phosphorus chemistry and opens up the possibility to synthesize functional phosphorus polymers of controlled architectures.
