Polyurethanes, chiral recognition

Polyurethanes (13) have been prepared with optically active diols and various diisocyanates.69 Chiral recognition depends on the diisocyanate... [Pg.166]

Several polyamides and polyurethanes have been synthesized by condensation polymerization and used as the precursors for the preparation of different CSPs. These CSPs showed different chiral recognition properties than those of addition polymers. AUenmark and Andersson [67] prepared a CSP containing silica gel supported by v-triazinc derivatives of L-valine isopropyl esters (Fig. 14) and the... [Pg.333]

Various optically active polyurethanes 15 were also synthesized from chiral diols and various diisocyanates to be used as CSPs [31]. The polyurethanes derived from aliphatic diisocyanates show better chiral recognitions than those from aromatic diisocyanate. [Pg.401]
