ABSTRACT:
An improved superabrasive composition for grinding applications comprising a superabrasive material, a bismaleimide-triazine addition copolymer resin which as a cured polymer exhibits (i) a glass transition temperature (Tg) of at least about 280.degree. C. and (ii) a long term thermal resistance of at least about 180.degree. C., a free radical generating initiator, and preferably a catalyst, is disclosed. The superabrasive abrasive composition is particularly useful as a cutting edge in a high performance cutting wheel.
