The present invention relates to novel structural classes of phenalkamines, a phenalkamine curing agent composition, a method for preparing such phenalkamines, and a method for preparing the composition. The phenalkamine curing agent composition of the present invention can be prepared by making cardanol react with a mixture of an aldehyde compound and a methylene crosslinked poly(cycloaliphatic-aromatic)amine. The curing agent composition may be used to cure, harden, and/or crosslink epoxy resins. 본 발명은 신규한 구조 계열의 페날카민, 페날카민 경화제 조성물, 이러한 페날카민의 제조 방법, 및 이러한 조성물의 제조 방법에 관한 것이다. 본 발명의 페날카민 경화제 조성물은 카르다놀을 알데히드 화합물 및 메틸렌 가교된 폴리(시클로지방족-방향족)아민의 혼합물과 반응시킴으로써 제조될 수 있다. 이러한 경화제 조성물은 에폭시 수지를 경화, 하드닝, 및/또는 가교시키는 데 사용될 수 있다.
