Aqueous adhesive solutions without solvent

(J/su) UHU GmbH, B?hl, Baden Abstract The invention provides novel aqueous adhesive solutions which do not contain any organic solvent. These solutions are entirely clear and show the perceptible tackiness desired by the consumer. The solutions contain mixed polymers comprising acrylic acid, vinyl acetate and a monomeric surfactant copolymerisable therewith which is selected from certain types of compounds as effective adhesive components. One of the selected types of compounds is a polyoxyethylene-allyl alcohol (polyoxyethylene glycol allyl ether) of the formula IA below (IA) or its methyl ether of the formula IB below (IB) where n = 2 to 50. The adhesive solutions can be prepared in a simple manner by initially introducing an aqueous solu-tion of a surfactant and metering in the acrylic acid partially neutralised with NaOH in the form of an aqueous solution and the vinyl acetate and, if desired, a further ethylenically unsaturated comonomer over a period of several hours. The reaction is advantageously carried out at temperatures in the range from 70 to 85°C. In the case of higher monomer concentrations, molecular weight regulators, such as polyglycols and/or acetates thereof, can additionally be used in the reaction batch. In this manner, the solids content of the adhesive solution can be adjusted to the desired value in a simple manner.
