Damaged composites are repaired by use of a rubber modified vinyl ester resin composition as either an adhesive for bonding metal or cured composite to the area surrounding the damaged area or by placing an uncured reinforcing material saturated with a rubber modified vinyl ester resin composition over the prepared damaged zone and curing in place.

Method for repairing damaged composite articles

The present invention is directed to polyurethane compositions containing triazine or both triazine and oxazoline or imino carbamate groups which are prepared by reacting:

Polyurethanes containing triazine or both triazine and oxazoline,

Imide functional polyphenols are prepared by reacting an excess of a phenol with an unsaturated diimide which is prepared by reacting an unsaturated polycycloaliphatic dicarboxylic acid anhydride with a diamine. These materials are useful in the preparation of castings, coatings, laminates and the like.

Imide functional polyphenols; thermosettable compositions containing

Poly(sulfide carbonate) compositions are prepared by reacting a bis(allyl)carbonate with a sulfur dihalide and optionally also with a bis- or polyallyl compound.
