Synthesis of amino‐containing syndiotactic polystyrene as efficient polymer support for palladium nanoparticles

Abstract

Amino-containing functionalized syndiotactic polystyrenes with high melting temperatures and temperature stability are synthesized by the direct polymerization of amino-containing styrenic monomers in the presence of a half-sandwich scandium catalyst system [(C5Me4SiMe3)Sc(CH2C6H4NMe2-o)2]/[Ph3C][B(C6F5)4]. The high syndiotactic poly(N,N-dimethylamino)styrene (rrrr > 99%), then used as novel polymer supports, effectively anchored Pd nanoparticles (3 wt % of Pd) with a diameter of 4 or 5 nm that were uniformly dispersed on polymer matrix.
