Hard capsules containing polymers and vinyl esters and polyethers, their use and manufacture

摘要

The present invention relates to hard capsules containing DOLLAR A (A) polymers which are obtainable by free-radical polymerization of DOLLAR A a) at least one vinyl ester in the presence of DOLLAR A b) polyether-containing compounds and DOLLAR A c) optionally one or more further copolymerizable monomers c ) and subsequent at least partial saponification of the ester functions of the original monomers a), DOLLAR A with the proviso that, in the absence of a further copolymerizable monomer c), the polyether-containing compound b) must have an average molecular weight of 10,000. DOLLAR A (B) optionally structure-improving auxiliaries and DOLLAR A (C) other customary shell components, their production and use.
