✦ Synopsis
Abstract
A series of hybrid materials, bearing neodymium silylamide initiating groups, have been shown to mediate isoprene polymerization when combined with alkyl aluminum activators [methylaluminoxane, AlEt~2~Cl, Al(i__Bu)~3~]. The surface species nature and relative distribution were correlated with isoprene polymerization activity and selectivity. This approach to stereocontrol modulation has been extended to racemic β‐__butyrolactone isoselective ring opening polymerization.
