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 formulaA represents hydrogen or an alkyl group with 1–3 C atoms, and individual A groups may be differentR 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. andn is 1, 2, 3 or 4.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:a) a first compound (the HVE-compound) containing at least one hydroxyl group and at least one vinyl ether group, andb) a second compound (the D/HIC-compound), being an isocyanate, reacting with formation of one or more urethane group(s), andc) a third compound (the G/P/HP-compound) chosen from the groups of (1) C2-6glycols, (2) C5-20polyols having 2–5 hydroxyl groups and (3) hydroxyl terminated polyester compounds, not being alkyd resins, having 1–5 free hydroxyl groups and from 2–50 monomeric ester units (the G/P/HP-compound), or mixtures thereof.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.
