Definitions
- graft polymers containing water-soluble or water-dispersible polyether blocks as coating and packaging means for washing, cleaning and laundry treatment agents
- the invention relates to the use of graft polymers containing water-soluble or water-dispersible polyether blocks as coating agents for particulate detergents and cleaning agents and as packaging material for detergents, cleaning agents and post-treatment agents for the production of individual portions for metering the agents in the washing process together with the Packing material.
- films made of water-soluble polymers such as polyvinyl alcohol or mixtures of polyvinyl alcohol, which can be obtained by 85 to 90% hydrolysis of polyvinyl acetate and acrylic acid, have been used, cf. JP-A-61-057 700 and DE-A-31 48 931.
- detergents are packaged in foil bags made from the polymers mentioned and added to the washing machine in the form of individual sealed packs. If they come into contact with water, the foil bags disintegrate and release the detergent contained in them.
- films made from polyvinyl alcohol have the disadvantage that they stick to one another in a moist environment, in particular when several bags of polyvinyl alcohol containing a detergent lie one above the other.
- EP-A-0 479 404 In order to reduce the stickiness of water-soluble films made of polyvinyl alcohol for the packaging of detergents and cleaning agents, it is known from EP-A-0 479 404 to combine a base film made of polyvinyl alcohol on at least one surface with a second plastic material, the less is water-soluble as polyvinyl alcohol and is present in the form of a discontinuous, at least partially non-particulate layer on at least the outer surface of the film.
- polyvinyl alcohol as packaging film has the disadvantage that the polyvinyl alcohol does not always completely dissolve in the washing liquor, tends to gel and is deposited on the laundry.
- polyvinyl alcohol has a slow dissolution rate and tends to become brittle and the flexibility decreases dramatically in low ambient humidity. That is why polyvinyl alcohol is usually added to plasticizers in the form of low molecular weight compounds. This required Chen plasticizers often pass from the casing into the contents and lead to changes there. The shell becomes poor in plasticizers and becomes brittle and unstable during storage.
- DE-B-1 077 430 discloses a process for the preparation of graft polymers of vinyl esters, in which polyalkylene glycols and / or their derivatives are dissolved in at least one vinyl ester, if appropriate in the presence of further solvents, and the solution is polymerized by free radicals.

The proportion of polyalkylene glycol in the graft polymer is 0.1 to 50% by weight.
- the modified polyvinyl alcohols are colorless to slightly colored loose powders that easily dissolve in water. They are used, for example, for the production of water-soluble packaging films, as sizing and finishing agents and for cosmetic articles.
- DE-B-1 094 457 discloses modified polyvinyl alcohols which consist of a graft polymer of at least one vinyl ester and optionally other monomers which can be copolymerized therewith on polyalkylene glycols, the graft polymer having been saponified to such an extent that the modified polyvinyl alcohol formed is already cold Water is soluble, but contains less than 50 wt .-% of polyvinyl alcohol units.

They are also used as a material for the production of softer, slightly water-soluble, clear transparent films, used as sizing and finishing agents and in cosmetics.
- graft polymers which are prepared by grafting polyalkylene oxides with vinyl acetate and whose vinyl acetate units are optionally saponified up to 15%, as graying inhibitors in the washing and aftertreatment of textile goods containing synthetic fibers.
- WO-A-00/18375 discloses the use of graft polymers of vinyl esters on the polyethers defined in more detail therein, such as polyalkylene glycols as coating agents, binders and / or film-forming auxiliaries in pharmaceutical dosage forms.
- the present invention is based on the object of avoiding skin contact of the user with the agents when dispensing detergents, cleaning agents and laundry post-treatment agents and to provide packaging material for portionwise metering of the agents, which is in the washing machine in contact with water the agent releases and is soluble or dispersible in water.
