  • Patent number: 6046297
    Abstract: Polyurethane prepolymers are disclosed prepared with mononuclear aromatic diisocyanate such as toluene diisocyanate and an aliphatic diisocyanate such as H12MDI. These prepolymers can be cured with 4,4'-methylene-bis-(3-chloro-2,6-diethylaniline) to form a cured urethane elastomer with reduced propensity to crack during the curing process, extended pour life (a slower rate of viscosity buildup after curative and prepolymer are mixed), low hysteresis, and a low level of free toluene diisocyanates and/or other toxic or volatile substances to increase worker safety during processing. It has also been found that prepolymers made from toluene diisocyanate and cured with a blend of two aromatic diamine curatives yields urethane elastomers with the same reduced propensity to crack during the curing process.

  • Patent number: 5990310
    Abstract: A method for preparing substituted triazines includes reacting a phenylazoaniline with a cyanuric halide to produce a (phenylazo) phenylamino-1,3,5-triazine, which is then reduced to form an aminoanilino-1,3,5-triazine. The aminoanilino-1,3,5-triazine can be alkylated under reducing conditions to produce an N-alkyl-phenylenediamino-1,3,5-triazine such as 2,4,5-tris-[N-alkyl-p-phenylenediamino]-1,3,5-triazine, which is useful as an antiozonant in rubber and other polymer formulations.
