    摘要： Silane-modified polyvinyl alcohol mixtures comprising: a) a low molecular weight, silane-containing polyvinyl alcohol having a Höppler viscosity according to DIN 53015 as a 4% by weight aqueous solution of from 1 to 25 mPas, and b) a higher molecular weight, silane-containing polyvinyl alcohol having a Höppler viscosity according to DIN 53015 as a 4% by weight aqueous solution of from 10 to 50 mPas, the silane-containing polyvinyl alcohol a) having a lower Höppler viscosity than the silane-containing polyvinyl alcohol b), are useful as non-dilatant polymeric binders for paper coating slips.
