摘要:
The invention relates to silane-modified polyvinylalcohols which are obtained by means of radical polymerisation by one or several vinyl esters in the presence of epoxide functional comonomers, subsequently silylation of the epoxide groups by means of nucleophilic silane compounds, and saponification of the silane-modified vinylester mixed polymers.
摘要:
The invention provides paper coating slips comprising, as a binder, an aqueous dispersion of a styrene-butadiene copolymer or of a styrene-acrylic ester copolymer, or a mixture of these aqueous dispersions, characterized in that an aqueous dispersion of a polyvinyl alcohol-stabilized vinyl acetate-ethylene copolymer is additionally present in each case.
摘要:
The invention relates to silane-modified polyvinyl alcohols obtained by treatment of vinyl alcohol polymers with one or more ethylenically-unsaturated silane-containing monomers at elevated temperature.
