Abstract: The invention relates to two-component chemical fastening systems, the A-component containing an unsaturated polyester and a reactive diluent, and the B-component containing a peroxide and an extender, wherein the extender is either a monomeric component according to formula 1 (A—CH?CH—O)n—R ??(formula 1) or a resinous compound comprising, in a covalently built-in manner, a component having vinyl ether group(s), and the content of the peroxide in the B-component is from 0.5 to 99 wt. %. In the formula A, R and n are specified as hydrogen or C1-3 alkyl; C1-20 (hetero)-aliphatic with hydroxyl or amino groups, or poly(C2 or 3)glycol with 2–120 glycol units; and 1 to 4, respectively. The resinous compounds with built-in vinyl ether group(s) (0.5 to 50 wt.

Abstract: The invention relates to peroxide compositions comprising a reactive diluent for the peroxide, wherein the diluent is either a component containing one or more vinyl ether group(s) and having a monomeric structure according to formula 1, (A—CH?CH—O)n—R, or is a suitable resinous compound comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s). In the formula A represents hydrogen or an alkyl group with 1–3 C atoms, and individual A groups may be different R either represents an aliphatic group, optionally branched, with 1–20 C atoms, etc. ?or represents a polyethylene or polypropylene glycol with 2 to 120 glycol units, etc. and n is 1, 2, 3 or 4.

Abstract: The invention relates to curable resin compositions based on an unsaturated prepolymer, a vinyl ether monomer that can be cross-linked with it and one or more other monomers for use as structural resins. The resin composition is cured with the aid of a radical-forming system that is unstable in the temperature range of −20° C. to +110° C., and contains an unsaturated prepolymer having an acid number of less than 10 mg of KOH per g and a vinyl ether monomer according to formula (I) or (II): A—CH═CH—O—R  (I) or (A—CH═CH—O)n—R′  (II) with A, R, R′ and n having the described meanings. The invention also relates to a process for the preparation of such resin compositions and uses thereof.

Abstract: The invention relates to peroxide compositions comprising a reactive diluent for the peroxide, wherein the diluent is either a component containing one or more vinyl ether group(s) and having a monomeric structure according to formula 1 (A—CH═CH—O)n—R, or is a suitable resinous compound comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s).

Abstract: The invention relates to radically curable resin mortars, containing unsaturated polyester and a reactive diluent, for use as A-component in two-component (+B-component containing peroxide and possibly an extender) for chemical fastening systems, wherein the diluent in the A-component is either a monomeric component according to formula 1

Abstract: 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 C2-6 glycols, C5-20 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.
