摘要：
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
(A-CH=CH-O) n -R (formula 1)
or a resinous compound, in which a monomeric component having vinyl ether group(s) has been built-in covalently, and the content of the component containing one or more vinyl ether group(s) being from 0.5 to 50 wt.%, calculated (as indicated) as weight percentage relative to the resin composition. A, R and n are specified as hydrogen or C 1-3 alkyl; C 1-20 (hetero)-aliphatic with hydroxyl or amino groups, or poly(C 2 or 3 )glycol with 2-10 glycol units; and 1 to 4, respectively.
The resinous compounds with buit-in vinyl ether group(s) (0.5 to 50 wt.%, calculated as indicated).are obtained by reaction of a mixture of appropriate amounts of:
a) a first compound (HVE) containing hydroxyl group(s) and at least one vinyl ether group, and
b) a second compound (D/HIC), being an isocyanate; and
c) a third compound (G/P/HP) from (1) C 2-6 glycols, (2) C 5-20 polyols having 2-5 hydroxyl groups and (3) hydroxyl terminated polyester compounds, not being alkyd resins, having 1-5 free hydroxyl groups and 2-50 monomeric units, or mixtures thereof.
The invention also relates to two-component chemical fastening systems comprising such curable mortar and a B-component, as well as to methods of preparing such mortars and use thereof for chemical fastening.
