Abstract

Solid compositions are prepared by reacting (A) one or more materials containing an average of more than one 1,2-epoxy groups with (B) one or more materials containing an average of more than one phenolic hydroxy groups wherein at least one of (A) or (B) contains with respect to (B) or has been prepared from with respect to (A) a reaction product of (1) at least one aromatic compound having at least one aromatic ring, at least one aromatic hydroxyl group and which aromatic ring contains at least one ortho or para position which is capable of being alkylated and (2) at least one aliphatic or cycloaliphatic C.sub.4 -C.sub.6 unsaturated hydrocarbon or a dimer, codimer, oligomer or cooligomer thereof.
