Abstract
The synthesis of some crosslinked polymers based on a segmented-chain polymeric mesogen contg. variable amts. of a side-chain substituent is reported. The unswollen networks show thermotropic mesomorphism of nematic character whose stability decreases with increasing substitution and crosslink d. Depending on the same parameters, the swollen networks may show optical anisotropy at room temp.--whose origin is attributed to phase sepn.File in questo prodotto:
