Abstract:
An adhesive containing a copolymer comprising the following structural units:(a) a unit corresponding to formula (I) and (b) a unit corresponding to formula (II) wherein m and p are each, independently of one another, selected from any whole number greater than zero; 1wherein n is 1;wherein o is 1 or zero; wherein Y is either a bond or a group of the formula â€”CRâ€²2â€”or â€”COâ€”Oâ€”CR2â€”CR2â€”CR2â€”; wherein each R radical, independently of one another, is selected from the group consisting of hydrogen, alkyls, groups of the formula â€”CRâ€²2â€”ORâ€², â€”ORâ€²,â€”COORâ€², SiRcRdRe, and â€”NRdâ€”Re, organic acid, anhydride, a readily hydrolysable ester of the formula â€”Oâ€”COâ€”Rc, a readily hydrolysable amide of the formula â€”NRdâ€”COâ€”Rc, a phenyl group, a group of the formula â€”CReRfCHRgâ€”SiX3, a group of the formula â€”SiOSiO(SiO)mH, an epoxy group, an aziridine group, a phosphate, a phosphonate group or an anhydride thereof, and a bond, or wherein two R radicals together represent a group of the formula &boxH;CR2; wherein each of the radicals Râ€²,Rc, Rd, Re, Rf, Rg and X are, independently of one another, selected from the group consisting of hydrogen, â€”OH, alkyls, alkoxy groups and aryl groups; with the proviso that in at least one unit of formula II, at least one of the R radicals bonded to a Si atom is selected from the group consisting of â€”OH, â€”ORc, â€”NRdRe, â€”OCORc, and â€”NRdCORe.
