Abstract
Sposób wytwarzania fotoreaktywnego, sieciowanego promieniowaniem ultrafioletowym hydrożelu samoprzylepnego, według wynalazku, charakteryzuje się tym, że poddaje się rodnikowej polimeryzacji rozpuszczalnikowej 50 do 85% wagowych alkilowych estrów kwasu akrylowego o długości od 2 do 12 atomów węgla w łańcuchu bocznym, 15 do 45% wagowych kwasu akrylowego, 0,05 do 5% wagowych zdolnego do kopolimeryzacji nienasyconego fotoinicjatora, przy czym sumaryczne stężenie wszystkich składników wynosi 100% wagowych. Następnie tak uzyskany kopolimer poliakrylanowy poddaje się modyfikacji etoksylowanymi aminami lub diaminami oraz wodorotlenkami metali jednowartościowych. Etoksylowane aminy lub diaminy stosuje się w ilości od 70 do 150% wagowych w odniesieniu do masy modyfikowanego kopolimeru, a wodorotlenki metali jednowartościowych stosuje się w ilości od 0,3 do 5,0% wagowych w odniesieniu do masy modyfikowanego kopolimeru. Następnie sieciuje się promieniowaniem UV uzyskując fotoreaktywny, usieciowany promieniowaniem UV hydrożel samoprzylepny.The method for the production of the photoreactive, ultraviolet-ray cross-linked pressure sensitive hydrogel according to the invention is characterized in that 50 to 85% by weight of acrylic acid alkyl esters with a length of 2 to 12 carbon atoms in the side chain, 15 to 45% by weight of acid are subjected to radical solvent polymerization. % acrylic, 0.05 to 5% by weight of a copolymerizable unsaturated photoinitiator, whereby the total concentration of all components is 100% by weight. Then, the polyacrylate copolymer thus obtained is modified with ethoxylated amines or diamines and with hydroxides of monovalent metals. Ethoxylated amines or diamines are used in an amount of 70 to 150 wt.% Based on the weight of the modified copolymer, and monovalent metal hydroxides are used in an amount of 0.3 to 5.0 wt.% Based on the weight of the modified copolymer. Then, it is cross-linked with UV radiation to obtain a photoreactive, self-adhesive hydrogel cross-linked with UV radiation.
