If the polymer is produced from the monomer by UV irradiation, a plasticizer which is sufficiently stable against UV light must be chosen, which in addition does not disturb the UV-induced polymerization.
- the plasticizer is hydrophilic and immiscible with water indefinitely.
- Suitable plasticizers are, for example, alcohols, polyalcohols, such as glycerol and sorbitol, glycols and ether glycols, such as mono- or diethers of polyalkylene glycols, mono- or diesters of polyalkylene glycols, polyethylene glycols, polypropylene glycols, mixed polyethylene and propylene glycols, glycolates, glycerol, sorbitan esters, and citric acid. and tartaric acid esters or imidazoline-derived amphoteric surfactants.
- preferred Plasticizers are polyalcohols such as glycerine and sorbitol, polyethylene glycol and their mixtures. Particularly preferred is glycerin.
- hydrocarbons and hydrocarbon mixtures such as white oil, in particular medicinal white oil or liquid paraffin.
- the plasticizer is usually added in an amount sufficient to achieve the desired glass transition temperature reduction.
- Typical levels of plasticizer are 5 to 50 parts by weight, preferably 8 to 40 parts by weight, in particular 10 to 30 parts by weight of plasticizer, based on 100 parts by weight of monomer i).
- the composites according to the invention are outstandingly suitable for moisture regulation, in particular in mattresses and seat cushions, for example in car seats.
- Seat cushions or mattresses containing the composites of the present invention increase sitting comfort by controlling the relative humidity to a comfortable level and preventing excessive perspiration.
- the composites of the invention can optimally release the absorbed moisture in phases of non-use and regenerate quickly.
- the composites according to the invention enable a hitherto unattainable sitting or lying comfort.
- the composites are stored for 60 minutes at a temperature of 23 0 C and a relative humidity of 50% in the climate chamber for equilibrium. Subsequently, the relative humidity is increased to 90% and the composites for 90 minutes at 30 0 C maintained (absorption phase). The relative humidity is then reduced to 40% and the sample is kept at 40 ° C. for 100 minutes (desorption phase).
- the weight change by absorption / desorption is measured continuously and as an increase in weight, based on g applied substance (water-absorbing polymer and / or salt).
- the reference point for weight gain is the weight after equilibration after 60 minutes.
- a monomer solution was sprayed and cured by UV radiation for 2 minutes. It was then dried for 5 minutes at 90 ° C. in a countercurrent dryer.
- the monomer solution contained 19599 g of a 37.5% strength by weight aqueous sodium acrylate solution (corresponding to 24.5% by weight of sodium acrylate in the entire monomer solution), 435 g of acrylic acid (8.5% by weight), 900 g of polyethylene glycol diacrylate (Diacrylate of a polyethylene glycol having an average molecular weight of 400) (3% by weight) as a crosslinker, 66 g of 2-hydroxy-1- [4- (hydroxyethoxy) phenyl] -2-methyl-1-propanone (0, 22 wt .-%) as an initiator, 1500 g of glycerol [5 wt .-%) and 7500 g of a 25 wt .-% aqueous sodium chloride solution (6.25 wt .-% NaCl).
- the amount of monomer solution was chosen so that the loading of the polymer terephthalate non-woven with polymerized water-absorbing polymer was 160 g / m 2 .
