Abstract: Cationic polyvinyl acetals are prepared by copolymerizing one or more cationic N-alkyldiallylammonium salt monomers with one or more vinyl esters of branched or unbranched carboxylic acids having 1 to 15 carbon atoms, hydrolyzing the resulting copolymers to copolymers containing ?50 mol % vinyl alcohol units, and acetalizating the vinyl alcohol units with one or more aliphatic aldehydes having 1 to 15 carbon atoms, their acetals, and/or hemiacetals, wherein the copolymerization takes place in a mixture of water and monovalent aliphatic alcohol having a water content of 2% to 35% by weight.

Abstract: Low molecular weight polyvinyl acetals have a solution viscosity of from 2 to 12 mPas and a degree of polymerization Pw less than 200, and are obtained by hydrolyzing a vinyl ester polymer having a solution viscosity of from 1.0 to 1.6 mPas until the content of vinyl alcohol units is ?50 mol %, to produce a polyvinyl alcohol whose solution viscosity is from 1.0 to 2.0 mPas, and then acetalizing the resultant polyvinyl alcohol. The products may be used as binders and films of increased adhesion to substrates.

Abstract: Silane-modified polyvinyl acetals are obtained by copolymerizing a) vinyl esters of C1-15 alkylcarboxylic acids having from 1 to 15 carbon atoms, and optionally (meth)acrylates C1-15 of alcohols, olefins, dienes, vinylaromatics, or vinyl halides, with b) from 0.02 to 20.0 % by weight of an ethylenically unsaturated, hydrolyzable silicon compounds or hydrolyzable mercaptosilanes; hydrolyzing the resulting vinyl ester copolymers to 50 mol % or more of vinyl alcohol units; and acetalizing vinyl alcohol units with a C1-15 aliphatic or aromatic aldehydes, wherein from 5 to 50 % by weight of a mixture of comonomers a) and silane comonomers b), based on the total weight of comonomers a) and b), is used as an initial charge, and the remainder is metered in during polymerization, such that the ratio between the comonomers a) and silane comonomers b) remains constant throughout the polymerization, resulting in a homogeneous polymer.

Abstract: A device is disclosed for draining flexible fluid containers, in particular blood bags which form part of an extracorporeal system in a single needle-type arrangement, having a movable plate (4b) and a fixed plate (4a) in which both plates are configured to confront a flexible fluid container. A force member (14), and a force transfer means (8, 18), are arranged in such a way that the force acting upon the movable plate (4b) increases as the container is drained.
