ABSTRACT:
The invention relates to α-ethoxysilane modified polymers of the average general formula (I):in whichR is a mono- to tetravalent polymer radical, not more than a third of the radicals R1, R2, and R3present in the polymer of the formula (I), independently of one another, are alkyl radicals having 1 to 4 carbon atoms, at least a quarter of the radicals R1, R2, and R3present in the polymer of the formula (I), independently of one another, are ethoxy radicals, any remaining radicals R1, R2, and R3, independently of one another, are methoxy radicals, and in which n is 1 to 4. The invention further relates to a process for preparing the polymers of the formula (I), and also to their use in adhesives, sealants, and coating materials.
