Described are matrix binders comprising copolymers based on amino-containing polymers, as well as their use in preparing active compound-containing granules and administration forms n The copolymers having basic amino groups can be obtained by radical polymerization of:n a) N,N-diethylaminoethyl methacrylate, and b) at least one radically polymerizable compound, selected from esters of α,β-ethylenically unsaturated mono- and dicarboxylic acids with C 1 -C 8 alkanols. |
