  • Patent number: 6762274
    Abstract: The present invention discloses a process for producing a polyurethane product with autocatalytic polyols. These auto-catalytic polyols are based on an initiator of the formula (I): HmA-(CH2)n—N(R)-(CH2)p-AHm where n and p are independently integers from 2 to 6, A at each occurrence is independently oxygen, nitrogen or hydrogen, with the proviso that only one of A can be hydrogen at one time, R is a C1 to C3 alkyl group, m is equal to 0 when A is hydrogen, is 1 when A B is oxygen and is 2 when A is nitrogen; or are polyols which contain an alkyl amine of within the polyol chain or a dialkylylamino group pendant to the polyol chain wherein the polyol chain is obtained by copolymerization of at least one monomer containing an alkyl aziridine or N,N-dialkyl glycidylamine with at least one alkylene oxide. These auto-catalytic polyols are reacted with a polyisocyanate in the presence of other additives and/or auxiliary agents known per se to produce polyurethane products.

  • Patent number: 6479614
    Abstract: An energetic copolyurethane thermoplastic elastomer (ETPE) is prepared by polymerizing a dihydroxyl terminated telechelic energetic polymer having a functionality of two or less with a diisocyanate at a NCO/OH ratio of about 0.7 to 1.2. The resulting copolymer is easy to incorporate in gun propellant or explosive formulations and is recyclable. These energetic copolyurethane thermoplastic elastomers were obtained mainly by macropolymerization of GAP prepolymers with 4,4′-methylenebis-phenyl isocyanate (MDI). In these syntheses, GAPs having molecular weights of 500, 1000 and 2000 were used as macromonomers and polymerized with MDI to yield three different copolyurethane thermoplastic elastomers. This process may be applied to any dihydroxyl terminated energetic prepolymers. The hard segments of the ETPE are obtained by the formation of hydrogen bonds between the urethane groups.
