    Abstract: IN PAPER COATING COMPOSITIONS, SYNTHETIC RESIN DISPERSIONS OF THE BASIS OF VINYL ACETATE/ETHYLENE COPOLYMERS WHICH MAY CONTAIN A MINOR PROPORTION OF FURTHER COMONOMERS, SUCH AS ACRYLIC ACID ESTERS OR AMIDES, DIENES, CROSSLINKING AGENTS, CAN BE COMBINED WITH WATER-SOLUBLE BINDERS, SUCH AS STARCH, CASEIN, AND POLYVINYL ALCOHOL. THIS IS ACHIEVED BY ADDING TO THE DISPERSIONS AFTER THE POLYMERIZATION, OR TO ANY ONE OF THE COMPONENTS OF THE COATING COMPOSITION IN THE COURSE OF ITS PREPARATION, A NON-IONIC WETTING AGENT WHICH IS A POLYETHYLENE OXIDE OR A POLYPROPYLENE OXIDE, OR BLOCK COPOLYMER OF ETHYLENE OXIDE AND PROPYLENE OXIDE, OR AN OXETHYLATED ALKYL PHENOL OR ALCOHOL OR ACID, OR A GRAFT POLYMER OF VINYL ACETATE AND CERTAIN OTHER MONOMERS ON POLYETHYLENE OXIDE. THE RESULTING COATING COMPOSITIONS EXHIBIT A HIGH PIGMENT CONTENT AT A RELATIVELY LOW VISCOSITY.

    Abstract: Unsaturated acetoacetic acid esters are suitable as comonomers in the polymerization of unsaturated compounds in an aqueous medium. Particularly suitable are acetylacetoxyalkyl-allyl ethers which may be synthesized in an easy manner and correspond to the formulae or Said allyl ether derivatives are especially prepared by reacting an allyl alcohol with an epoxide and reacting the resulting hydroxyalkyl-allyl ether with diketene. Both reaction steps are carried out at a temperature of from 0 DEG to 100 DEG C., preferably in the presence of a catalyst. The allyl ether derivatives may be copolymerized especially with vinyl compounds, such as vinyl esters, acrylic acid esters, olefins, vinyl halides and vinyl aromatic hydrocarbons.

    Abstract: Vinyl polymers with acetylacetoxy groups form the basis of polymer dispersions which are used as binding agent dispersions in paints, particularly suitable vinyl polymers are obtained by polymerizing an acetylacetoxy compound together with a least one further olefinically unsaturated compound, while using as acetylacetoxy compound an allyl ether derivative of the formula or The copolymerization is carried out in particular in emulsion at a temperature in the range of from -30 DEG to 200 DEG C. As comonomers there are used especially vinyl esters and (meth-)acrylic acid esters. The polymerization is commonly effected in the presence of a radical-forming initiator and optionally in the presence of emulsifiers and protective colloids.

    Abstract: 1408361 Vinyl ester copolymer powders HOECHST AG 4 May 1973 [5 May 1972] 21355/73 Heading C3P A water dispersible powdered copolymer is prepared by copolymerizing a vinyl ester and an acrylamide of the formula in which X is H or -CH 3 , Y is H or -CH 2 OZ, and Z is H, alkyl or acyl, each having up to 4 carbon atoms, in an emulsifier-free aqueous dispersion, and subsequently drying the dispersion to form a powder. Ethylene may be additionally copolymerized. Drying may be effected by freeze-drying, drum drying or fluidized bed spray granulation. The latter method may utilize air or nitrogen as the drying gas, which may be passed into the drying tower at a temperature of 90-110‹ C. A filler may be added before, during, or after drying. Specified monomers are: vinyl acetate, -laurate, -stearate, -butyrate and -propionate; and acrylamide, methacrylamide, N-methylol (meth) acrylamide, and (meth)acrylamide-N-methylolmethyl ether. In the example, vinyl acetate, acrylamide and ethylene are copolymerized in the absence of emulsifier, and spray dried.
