Abstract:
The present invention relates to compounds according to formula (I) and to heat-curable compositions based on polymaleimide resin systems comprising such compounds as co-monomers: wherein R 1  is hydrogen or an alkenylphenoxy group, R 2  is an alkenylphenoxy group, and R 3  is hydrogen or an alkyl group with 1 to 4 carbon atoms. The present invention also relates to cross-linked resins obtainable by curing such compositions. Compounds of the present invention can be used amongst others in fields like structural adhesives, matrix resins for fiber prepregs, moulding compounds, as well as structural and/or electrical composites.

Claim (Index 2):
The alkenylphenoxy-1,1-diphenylethylene of  claim 1 , wherein alkenylphenoxy groups R 1  and R 2  are independently selected from the group consisting of the following structures: in which the ALKENYL residue is a 1-alkenyl group with 2 to 6 carbon atoms or a 2-alkenyl group with 3 to 6 carbon atoms.
