Abstract
Specific anionic polyesters are described which are particularly suitable for use in fabric and home care compositions such as laundry detergent compositions. In such applications, the polyesters e. g. exhibit advantageous whiteness maintenance and have advantageous biodegradability.
Claims17
1-12. (canceled)
A polyester comprising
- A) one or more structural units of the formula (I)
- and
- B) one or more structural units of the formula (II)
- wherein
- 1/p Mp+ is a cation, selected from the group consisting of monovalent cations M+ (p=1), divalent cations ½ M2+ (p=2) and trivalent cations ⅓ M3+ (p=3),
- and
- C) one or more structural units of the formula (III)
- wherein R1 is a linear or branched alkylene group of the formula (CmH2m),
- where m is an integer from 2 to 12,
- and
- D) one or more terminal groups of the formula (IV)
- wherein
- R2 is a linear or branched C1-C30 alkyl group, a cycloalkyl group with 5 to 9 carbon atoms, or a C6-C30 arylalkyl group,
- n is an integer from 2 to 12, whereby the definition of n may vary within a single terminal group of the formula (IV), and
- x is, based on molar average, a number of at least 1,
- and
- E) one or more structural units of the formula (V)
- wherein
- n1 is an integer from 2 to 12, whereby the definition of n1 may vary within a single structural unit of the formula (V);
- d is, based on molar average, a number from 2 to 200;
- and
- the average number of moles of the one or more structural units of the formula (V) per mole of the polyester is equal to or greater than 0.3.
