11. Diamines are attached as carbamates to hydroxymethyl polystyrene resin.12. It is used as a chelating diamine for the preparation of metal catalysts. 13. Homopolymer polyamides derived from pairs of diamines and diacids ( or diacid derivatives ). 14. Its chemical properties resemble those for ethylene diamine , and it has similar uses. 15. The ruthenium diamine complexes form adducts with guanine. 16. The catalyst has chiral diamine auxiliaries that induces the asymmetric change in the cavity. 17. The developing ingredient is a paraphenylene diamine -based chemical known as CD-4. 18. The diamines in PPAs are aliphatic. 19. The polymer is prepared from the diamine bis ( para-aminocyclohexyl ) methane and dodecanedioic acid. 20. It is used to prepare a chelating diamine -containing ligands for the preparation of metal catalysts.
