Binding agents and binding agent compositions containing alkoxy silyl groups, methods of production and use

摘要

A binder which is a graft polymer bearing at least two alkoxysilyl groups of the formula -Si(R₁)_m(OR₂)_3-m in which R₁ and R₂ are independently linear or branched alkyl groups containing 1 to 6 carbon atoms and m is an integer of 0 to 2. The graft polymer has graft branches on a graft base. The graft polymer contains at least 0.5% by weight, based on the graft base, of graft branches.
