The present invention relates to a low-odor, polymerizable, cold-curing (meth)acrylate composition for floor coatings exhibiting low health hazards during application and consisting of (A) 50&#x2013;100 wt % a (meth)acrylate; (B) 0&#x2013;2 parts by weight per 1 part by weight of (A) of a pre-polymer that dissolves or swells in (A); (C) 2&#x2013;5 parts by weight per 100 parts by weight of (A+B) of at least one paraffin and/or wax; (D) a redox system, containing an accelerator and a peroxide catalyst or initiator in an amount that is adequate for cold-curing of Component A; and (E) a conventional additive.

Low-odor, cold-curing (METH) acrylate reaction resin for floor coating, a floor coating containing the reaction resin, and a process for the preparation of the floor coating

The invention relates to polymer beads having a high content of diacyl peroxides. A prolongation of the pot life in reaction resins based on high-boiling methacrylate esters is achieved due to this high content of peroxides.

Depot polymerization starter beads

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 -C alkyl acrylate, 99-1% by weight of C -C alkyl methacrylate, and 0-0.5% by weight of a first graft component, which is then swollen by a mixture of at least one ethylenically unsaturated monomer and a polymerization initiator. Component B also comprises an emulsion polymer formed by the polymerization of 1-99% by weight of C -C alkyl acrylate, 99-1% by weight of C -C alkyl methacrylate, and 0-0.5% by weight of a second graft component, swollen with at least one ethylenically unsaturated monomer and a polymerization activator. 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.

Aqueous monomer/polymer composition

A method of producing low-viscosity water-based water-soluble polymer dispersions having a high concentration of the principal substance is achieved by polymerizing the following monomer components, (a1) 50-99.999 wt. % of at least one water-soluble monomer; (a2) 0.001-1 wt. % of at least one crosslinking monomer with at least two ethylenically unsaturated radically polymerizable groups; (a3) 0-30 wt. %, particularly 1-25 wt. %, of at least one hydrophobic monomer; and (a4) 0-25 wt. %, particularly 0.1-15 wt. %, of at least one amphiphilic monomer, in aqueous solution, in the presence of at least one polymer dispersant, to form a polymer (A), where the sum of the amounts of the components represented by the monomers (a1), (a2), (a3), and (a4) is 100 wt. % of the monomers, the weight average molecular weight of the resulting polymer (A) is at least 500,000 Dalton, and polymer (A) is incompatible with the dispersant.
