The present invention relates to resin compositions for radical curing comprising a component (I) containing reactive carbon-carbon unsaturations and a component (II) containing XH-groups, with X not being C or O., which resin compositions (a) are substantially free of photoinitiators; (b.) have an average number of reactive carbon-carbon unsaturations of component (I) equal to or higher than 2; (c) have an average number of XH-groups of component (II) equal to or higher than 2; (d) whereby at least one of the average numbers of (b) and (c) is higher than 2; (e) and at most 5 mol% of the reactive unsaturations is capable of undergoing homopolymerisation; (f) respectively is present in the form of a mono-ene functional alkylene; and (g) the molar ratio of the XH-groups and of the reactive unsaturations is in the range of from 4 : 1 to 1 : 4.
The present invention also relates to processes for curing such resin compositions, in particular by cold curing. And finally, the present invention also relates to a new process for the synthesis of Diels-Alder adducts of cyclopentadiene and a resin component containing telechelic carbon-carbon unsaturation.
The resin compositions are capable of providing constructive materials with tack-free surfaces by fast, and tunable, radical curing, and without any problems of so-called oxygen inhibition. Suitable applications are in chemical anchoring, roofing, flooring, (re)-lining, SMCs and BMCs.
