Abstract

A jelen találmány tárgya eljárás a láncvégi izocianát-csoportokkalrendelkező poliuretán előpolimerek előállítására a poliizocianátokpoliolokkal történő reagáltatásával, azzal jellemezve, hogy (I) azelső szintézis lépésben a) poliizocianátként legalább egyaszimmetrikus diizocianátot használnak fel, b) polioiként legalább 60g/mol és 3000 g/mol közötti átlagos molekulatömege (Mn) polioltalkalmaznak, c) az izocianát-csoportok hidroxilcsoportokhozviszonyított arányát 1,5:1 és 3:1 közötti tartományon beül állítjákbe, d) katalizátorként szerves fémvegyületet vagy e-kaprolaktámotadnak hozzá, majd az azt követő reakció szerint (II) a másodikszintézis lépésben a) legalább egy további poliolt adnak hozzá olyanmódon, hogy az izocianát-csoportok hidroxilcsoportokhoz víszonyítottösszesített aránya 1,1:1 és 2:1 közötti tartományba essen. A találmánytárgyát képezi továbbá az ily módon előállított láncvégiizocianátcsoportokat tartalmazó poliuretán előpolimerek alkalmazásareaktív egy- vagy kétkomponensű ragasztó/tömítőanyag előállítására. Atalálmány szerinti eljárással előállított poliuretán előpolimerekalacsony viszkozitásúak, monomerben szegények és melléktermékektőlmentesek, mivel azok rendszerint a hőkezelési feldolgozásnál apoliuretán előpolimerek monomerekre való szétesését eredményeznék.
