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&#x2014;CH&#x2550;CH&#x2014;O)&#x2014;R &#x2003;&#x2003;(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 Calkyl; C(hetero)-aliphatic with hydroxyl or amino groups, or poly(C)glycol with 2&#x2013;120 glycol units; and 1 to 4, respectively. The resinous compounds with built-in vinyl ether group(s) (0.5 to 50 wt. %, calculated as indicated) are obtained by reaction of a mixture of appropriate amounts of: The invention also relates to methods for preparing (the B-component) of such two-component chemical fastening systems, as well as to use of the systems for chemical fastening.

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&#x2014;CH&#x2550;CH&#x2014;O)&#x2014;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 The resinous compounds comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s)are obtained by reaction of: The invention also relates to the preparation of such compositions and to the use of such reactive diluents for peroxides in radically curing of unsaturated polyester resins for structural applications.
