  • METHOD FOR THE INDUSTRIAL PRODUCTION OF 2-HALO-4,6-DIALKOXY-1,3,5-TRIAZINES AND THEIR USE IN THE PRESENCE OF AMINES
    Publication number: 20210355091
    Abstract: A method for stabilization of collagen matrices and of condensation of natural and synthetic polymers that uses 2-halo-4,6-dialkoxy-1,3,5-triazines in the presence of one or more amines as activating agents for reactions of crosslinking, condensation, grafting, and curing of collagen matrices, cellu lose, modified celluloses, polysaccharides, acid unsaturated polymers, and chiral and non-chiral amines, etc. Forming an integral part of the present invention is also the method for production on an industrial scale of 2-halo-4,6-dialkoxy-1,3,5-triazines.

  • Use of 2,4-dihalo-6-substituted-1,3,5-triazines and derivative thereof as condensation, cross-linking, tanning, grafting and curing agents
    Patent number: 11104767
    Abstract: Use of 2,4-dihalo-6-substituted-1,3,5-triazines as condensing, cross-linking, tanning, grafting, curing agents for the production of amides, esters, thioesters, and stabilized collagen and leather, CMC (carboxymethyl cellulose), synthetic and natural polymers. The process enables to obtain non-toxic and totally free of heavy metals products characterized by Tg values between 80° C. and 100° C.
