Claims
- 1. A polyol ether derivative represented by any one of the following general formulas (I) to (IV): ##STR61## wherein R.sub.1 represents a hydrogen atom, a linear alkyl group having 1-21 carbon atoms or a branched alkyl group having 3-21 carbon atoms; R.sub.2 represents a branched alkyl group having 3-17 carbon atoms when R.sub.1 represents a hydrogen atom, or R.sub.2 represents a linear alkyl group having 1-21 carbon atoms or a branched alkyl group having 3-21 carbon atoms when R.sub.1 represents a linear alkyl group having 1-21 carbon atoms or a branched alkyl group having 3-21 carbon atoms; R.sub.1 and R.sub.2 may together join to form a ring with an alkylene group having 2-13 carbon atoms; 2 to 6 pairs of R.sub.1 and R.sub.2 may be identical or different; k.sub.1 represents a number of 0-5, p.sub.1 represents a number of 0-2, m.sub.1 represents 0 or 1, wherein k.sub.1, p.sub.1 and m.sub.1 satisfy the equation k.sub.1 +(m.sub.1 +2)p.sub.1 =5; k.sub.2 and n.sub.2 each represents a number of 0-4, p.sub.2 represents a number of 0-2, m.sub.2 represents 0 or 1, wherein k.sub.2, p.sub.2, m.sub.2 and n.sub.2 satisfy the equation k.sub.2 +(m.sub.2 +2)p.sub.2 +n.sub.2 =4; R.sub.3 represents a hydrogen atom, a linear alkyl group having 1-8 carbon atoms or a branched alkyl group having 3-8 carbon atoms; and repeating units in formulas (I) and (II) may be arranged at random or in block form.
- 2. The polyol ether derivative according to claim 1, wherein an alcohol residue of the polyol ether derivative is derived from sorbitol.
