The invention relates to the use of vinyl acetate-copolymers as a shrinkage-reducing additive (low profile additive) in cold-curing systems for producing composite materials, characterized in that vinyl acetate-copolyerisate of 40 to 95 wt % vinyl acetate and 5 to 60 wt % of one or more co-monomers from the group containing vinyl esters of unbranched or branched carboxylic acids having 3 to 20 C-atoms and methacrylic acid esters and acrylic acid esters of unbranched or branched alcohols having 2 to 15 C-atoms are used, wherein the specifications in wt % relate to the total weight of the co-monomers and add up to 100 wt %.

Use of vinyl acetate-copolymers as a shrinkage-reducing additive in cold-curing systems

A method of producing composites from inorganic materials by processing with thermoplastic forming techniques mixtures containing one or more inorganic, fine residual materials and one or more polymers based on ethylenically unsaturated monomers in the form of protective colloid-stabilized, water-redispersible polymer powders, wherein the inorganic, fine residual materials are based on inorganic materials selected from the group consisting of gypsum, lime, talc, silicas, kaolins, silicates and titanium dioxide, and wherein the composites are based on from 5 to 80% by weight of polymers based on ethylenically unsaturated monomers and from 20 to 95% by weight of inorganic, fine residual materials, based on the total weight of polymer based on ethylenically unsaturated monomers and inorganic, fine residual materials.
