摘要： The invention relates to silicone-containing polyvinyl acetals that can be obtained by: 1) copolymerizing; a) one or more vinyl esters of unbranched or branched alkyl carboxylic acids having 1 to 15 C atoms, and; b) one or more silicone macromeres having at least one polymerizable group; 2) subsequently saponifying the copolymer to produce silicone-containing polyvinyl alcohol, and; 3) subsequently acetalizing the silicone-containing polyvinyl alcohol with one or more aldehydes from the groups containing aliphatic and aromatic aldehydes having 1 to 15 C atoms.
