Six chiral monomers (M-1-M-6), and their corresponding polymers (P-1, P-4) and elastomers (P-2, P-3, P-5, P-6) derived from chiral mesogenic crosslinking agent were synthesized. The chemical structures Of M-1-M-6 were confirmed by FTIR and H-1 NMR spectroscopy. The structure-property relationships Of M-1-M-6 and P-1-P-6 were discussed. Their mesomorphic properties and phase behavior were investigated by differential scanning calorimetry (DSC), thermogravimetric analyses (TGA), polarizing optical microscopy (POM), and X-ray diffractometer (XRD) measurements. All monomers obtained, except M-2 and M-5, showed typical oily streaks texture and focal conic texture of cholesteric phase on heating and cooling cycles. The selective reflection of cholesteric monomers and elastomers shifted to the short wavelength region with increasing temperature. The elastomers P-2 and P-5 did not reveal the mesomorphic properties, and P-3 and P-6 showed cholesteric phase. TGA showed that P-1-P-6 had a high thermal stability. (C) 2007 Wiley Periodicals, Inc.
