The invention relates to processes for preparing metal(IV) compounds which are suitable especially as catalysts for preparation of polyesters, polyurethanes and polysiloxanes, and to the use of the metal compounds for preparation of polyesters, polyurethanes or polysiloxanes.
The invention relates to radically curable resin compositions comprising at least a resinous component with one or more vinyl ether group(s), and one or more reactive monomers, wherein said resinous component is obtained by reaction of a mixture of appropriate amounts of a) a compound containing at least one hydroxyl group and at least one vinyl ether group; b) a diisocyanate (or higher isocyanate) compound, reacting with formation of one or more urethane group(s); and c) a compound chosen from the groups of C

polyols having 2-5 hydroxyl groups and (un)saturated hydroxyl terminated polyester compounds, with 1-5 free hydroxyl groups and from 2-50 monomeric ester units, the content of vinyl ether groups in the resin composition being from 0.5 to 50 wt. %, calculated as the weight percentage of the HVE-compound relative to the total weight of the resin composition (excluding the weight of additives, fillers and the like), the total acid number of the radically curable resin composition being less than 10 mg of KOH per g, and wherein the curing is effected with the aid of a radical-forming system that is unstable in the temperature range from −20° C. to +110° C.
The invention also relates to a process for the preparation of such resin compositions and uses thereof.
A storage stable monomer/polymer composition comprises a component A and a component B. Component A comprises an emulsion polymer formed by the polymerization of 1-99% by weight of a C

Curing of the monomer/polymer composition begins only after the water has evaporated from the dispersion. The aqueous monomer/polymer compositions are used as binders for road marking paints, floor coating compositions, coating materials and sealing compositions.
