Definitions

  • the present invention relates to certain monomers and polymers obtainable from renewable resources, to the use of such polymers for enhancing the primary detergency of laundry detergents or cleaners when washing textiles or cleaning hard surfaces, as well as detergents and cleaners containing such polymers.
  • Detergents contain in addition to the indispensable for the washing process ingredients such as surfactants and builder materials usually further ingredients that can be summarized by the term washing aids and include as different drug groups such as foam regulators, grayness inhibitors, bleach, bleach activators and dye transfer inhibitors.
  • Such excipients also include substances whose presence enhances the detergency of surfactants, without them usually having to exhibit a pronounced surfactant behavior itself. The same applies mutatis mutandis to cleaners for hard surfaces. Such substances are often referred to as Waschkraftverschreibr.
  • copolymers have the disadvantage that they are essentially completely composed of monomers which are produced petrochemically. There is a need for laundry performance polymers that are at least partially composed of monomers that can be made from renewable resources.
  • European Patent Application EP 3 009 430 A1 discloses that 2-vinyltetrahydrofuran-3,4-diol can be prepared from 1,4-sorbitan, 1,4-sorbitan from sorbitol and this from the renewable raw materials Glucose and fructose can be obtained.
  • copolymers of ethylenically unsaturated carboxylic acids and ethylenically unsaturated monomers which can be prepared from sugar alcohols have particularly good properties which enhance the performance of detergents and cleaners.
  • R 2 , R 3 and R 4 are the same;
  • at least one of the radicals R 2 , R 3 and R 4 is hydrogen.
  • Monomers of general formula I are accessible from sorbitol, xylitol or ribitol. They can be copolymerized in the presence of conventional free-radical initiators such as azobisisobutyronitrile or benzoyl peroxide with ethylenically unsaturated carboxylic acids or carboxylic acid derivatives, wherein the two hydroxyl groups in the polymerization by prior accumulation of conventional protecting groups, for example as acetal such as tetrahydropyranyl ether, as ketal such as acetonide or as a carboxylic acid ester such as acetate, can be protected and the protective groups removed after the polymerization again.

Abstract

L'invention vise à améliorer le pouvoir détergent de détergents et produits de nettoyage, en particulier vis-à-vis de salissures grasses et/ou huileuses. Ce but est atteint essentiellement grâce à l'incorporation de copolymères pouvant être obtenus par copolymérisation de composés représentés par la formule générale (I) dans laquelle R1 représente CR2=CR3R4 ou -CH2-O-CH2-CR2=CR3R4 et R2, R3 et R4 désignent indépendamment les uns des autres H ou un groupe alkyle ayant 1 à 3 atomes de carbone, avec des acides carboxyliques α,ß-monoéthyléniquement insaturés, des esters de ces acides carboxyliques, des anhydrides de ces acides carboxyliques, des amides de ces acides carboxyliques, des imides de ces acides carboxyliques, des nitriles et leurs mélanges.
