Abstract
A novel LCP material based on forked side chain acrylates is disclosed having a general formula I; ##STR1## wherein W=H, CH.sub.3, Cl R.sub.1 and R.sub.2 may or may not be the same but have the following general structure: ##STR2## p=2 to 14; q=0 or 1; r=1 or 2; s=1 or 2; X=O, CO.sub.2, O.sub.2 C, CH.sub.2 ; Y=C.sub.2 H.sub.4, O, CO.sub.2, O.sub.2 C; Z=CN, halogen, R, CO.sub.2 R, OR, O.sub.2 CR, wherein R=chiral or achiral.
