- 4. A polyester having a repeating unit represented by the following formula (6): ##STR21## wherein A is a polyol compound residue represented by the following formula (2) or formula (3): ##STR22## wherein R.sup.1 and R.sup.3 each individually represents an alkyl group having from 1 to 4 carbon atoms, and R.sup.2 and R.sup.4 each individually represents a hydrogen atom or a methyl group; and X represents an alkylene, cycloalkylene, arylene or arylalkylene group having from 1 to 12 carbon atoms.
- 5. The polyester as claimed in claim 4, wherein R.sup.1 in formula (2) is a methyl group.
- 6. The polyester as claimed in claim 4, wherein R.sup.3 in formula (3) is a methyl group.
- 7. A polyurethane having a repeating unit represented by the following formula (7): ##STR23## wherein A is a polyol compound residue represented by the following formula (2) or formula (3): ##STR24## wherein R.sup.1 and R.sup.3 each individually represents an alkyl group having from 1 to 4 carbon atoms, and R.sup.2 and R.sup.4 each individually represents a hydrogen atom or a methyl group; and Y represents an alkylene, cycloalkylene, arylene or arylalkylene group having from 1 to 12 carbon atoms.
- 8. The polyurethane as claimed in claim 7, wherein R.sup.1 in formula (2) is a methyl group.
- 9. The polyurethane as claimed in claim 7, wherein R.sup.3 in formula (3) is a methyl group.
- 10. A polyurethane obtained by polyaddition of a polyol compound to a polyisocyanate compound, wherein the polyol compound is entirely or partially a polyesterpolyol comprising a repeating unit represented by the formula (6): ##STR25## wherein A is a polyol compound residue represented by the following formula (2) or formula (3): ##STR26## wherein R.sup.1 and R.sup.3 each individually represents an alkyl group having from 1 to 4 carbon atoms, and R.sup.2 and R.sup.4 each individually represents a hydrogen atom or a methyl group; and X represents an alkylene, cycloalkylene, arylene or arylalkylene group having from 1 to 12 carbon atoms.
- 11. The polyester as claimed in claim 4, comprising a diol residue represented by formula (2) or (3) in an amount of from 5 to 100 mol % of all diol components contained in the polyester.
- 12. The polyester as claimed in claim 4, comprising a diol residue represented by formula (2) or (3) in an amount of 20 mol % or more of all diol components contained in the polyester.
- 13. The polyurethane as claimed in claim 7, comprising a diol residue represented by formula (2) or (3) in an amount of from 5 to 100 mol % of all diol components contained in the polyurethane.
- 14. The polyurethane as claimed in claim 7, comprising a diol residue represented by formula (2) or (3) in an amount of from 10 to 100 mol % of all diol components contained in the polyurethane.
- 15. The polyurethane as claimed in claim 10, comprising a diol residue represented by formula (2) or (3) in an amount of from 10 to 100 mol % of all diol components contained in the polyurethane.
- 16. The polyurethane as claimed in claim 10, comprising a diol residue represented by formula (2) or (3) in an amount of from 20 to 100 mol % of all diol components contained in the polyurethane.
