Claims
- 1. An alkenyl ether compound expressed by the formula
- R.sub.1 --CH.sub.2 --O--(CH.sub.2)n--A.sub.1 --A.sub.2 --A.sub.3 --R.sub.2[I]
- wherein R.sub.1 represents an alkenyl group of 2 to 7 carbon atoms having a double bond at its terminal or a double bond of a trans configuration at a position other than its terminal, R.sub.2 represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms, A.sub.1 and A.sub.2 each independently represent a 1,4-phenylene or a trans-1,4-cyclohexylene, A.sub.3 represents a 1,4-phenylene, a trans-1,4-cyclohexylene or a single bond and n represents 1 or 2.
- 2. An alkenyl ether compound according to claim 1, wherein said R.sub.1 represents CH.sub.2 .dbd.CH--.
- 3. An alkenyl ether compound according to claim 1, wherein said R.sub.1 represents (E)--CH.sub.3 CH.dbd.CH--.
- 4. An alkenyl ether compound according to claim 1, wherein said R.sub.2 represents an alkyl group or an alkoxy group each of 1 to 5 carbon atoms.
- 5. A liquid crystal composition comprising at least two components at least one of which is an alkenyl ether compound as set forth in claim 1.
