Abstract
Official abstract text for this publication.
The present invention relates to random copolymers obtainable by polymerization, the use of said random copolymers as soil release agents in laundry processes. Further aspects of the invention are a method for easier releasing soil from textiles in laundry processes and detergents containing said random copolymers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A random copolymer obtained by polymerization of (i) at least one monomer according to formula (I): in an amount of 38.5 to 70 mol %, wherein n is 3 to 23, and (ii) at least one monomer according to formula (II): in an amount of 30 to 61.5 mol %. 2. The random copolymer according to claim 1 , wherein n of the at least one monomer according to formula (I) is between 5 and 23. 3. The random copolymer according to claim 1 , wherein n of the at least one monomer according to formula (I) is selected from the group consisting of 7 and 23. 4. A soil release agent in aqueous laundry processes which comprises the random copolymer as defined in claim 1 . 5. A detergent comprising the random copolymer as defined in claim 1 . 6. The random copolymer according to claim 1 , wherein n of the at least one monomer according to formula (I) is from 3 to 23. 7. The random copolymer according to claim 1 , wherein n of the at least one monomer according to formula (I) is 7.
