Definitions

  • the present invention relates to a method of producing a phosphonated acrylic copolymer, and to the copolymer obtained by the method. Furthermore, the present invention pertains to the use of the phosphonated acrylic copolymer for hydrophilizing surfaces and to automatic dish washing and metal cleaning compositions comprising the phosphonated acrylic copolymer.
  • hydrophilization of surfaces via polymers is a common means in order to improve water spreading and thus the drain off of water from the surface, especially in cleaning applications like dishwashing or hard surface cleaning.
  • hydrophilizing surfaces less drying residues appear on reflective and transparent surfaces.
  • Such polymers often have no specific affinity to the surface and form a hydrophilic layer on the surface only via drying. Thereby, a rather high amount of polymer is needed. Furthermore, the effect is not long lasting as the polymer can be washed off.
  • the present inventors found that the problem can be solved by a novel phosphonated acrylic copolymer. Furthermore, it has been surprisingly found that with this copolymer a thicker layer on the surface can be obtained compared to already conventionally used polymers, when applied in the same amount. Furthermore, the copolymers according to the present invention form a longer lasting layer and the drain off of water in view of the initial stainless steel surface is improved. Finally, since phosphonic groups are employed to obtain the affinity to the surface, no environmental concerns arise compared with phosphates.
  • the present invention relates in a first aspect to a method of producing a phosphonated acrylic copolymer, comprising or consisting of the steps:
  • a phosphonated acrylic copolymer obtainable by the method according to the present invention is provided.

  • oxidoreductases for example oxidases, oxygenases, catalases (that react at lower H 2 O 2 concentrations than peroxidase), peroxidases, such as halo-, chloro-, bromo-, lignin-, glucose- or manganese-peroxidases, dioxygenases or laccases (phenoloxidases, polyphenoloxidases).
  • Suitable commercial products are Denilite® 1 and 2 from the Novozymes Company.
  • Example 1 Adsorption and retention of a polymer according to the present invention (C1) in comparison with the commercially available polymer Mirapol Surf S 110.
  • the copolymer was obtained by reacting 0.08 mol of the above-mentioned monomer mixture, 0.8 mmol AIBN and 0.02 mmol mercapto acetic acid in 81 mL dry DMF after degassing with nitrogen at 70 °C until complete conversion.
  • the polymer was precipitated in cold tert-butyl methyl ether.
  • the phosphate groups were hydrolyzed by dissolving the polymer in 73 mL anhydrous DCM and addition of 0.02 mol trimethyl silyl bromide. The solution was stirred for 24 h at ambient temperature and 50 mL methanol were added and stirred for another 3 h.
  • the resulting polymer was precipitated in cold hexane and dried under vacuum.
  • the resulting copolymer C1 had a number average molecular weight of 5.000 g/mol.
  • Solutions containing 0.3 wt.-% of the copolymer C1 or Mirapol Surf S 110 were obtained by dissolving the polymer in water (16°dH, pH value 3). The obtained solutions were tested for their adsorption value against steel (stainless steel) and SiO 2 via a quartz crystal microbalance (QCM). In the retention measurement the same solutions without polymer were employed to rinse the adsorbates.
