    Abstract: A bone cement is shown that includes a monomer, and a non-reactive substance that is fully miscible with the monomer. A resulting cured bone cement exhibits desirable properties such as modification in a stiffness of the material. Modified properties such a stiffness can be tailored to match bone properties and reduce an occurrence of fractures adjacent to a region repaired with bone cement. One example includes adjacent vertebral body fractures in vertebroplasty procedures.

  • Publication number: 20140024733
    Abstract: A polyether polyol based on renewable materials is obtained by the in situ production of a polyether from a hydroxyl group-containing vegetable oil, at least one alkylene oxide and a low molecular weight polyol having at least 2 hydroxyl groups. The polyol is produced by introducing the hydroxyl group-containing vegetable oil, a catalyst and an alkylene oxide to a reactor and initiating the alkoxylation reaction. After the alkoxylation reaction has begun but before the reaction has been 20% completed, the low molecular weight polyol having at least 2 hydroxyl groups is continuously introduced into the reactor. After the in situ made polyether polyol product having the desired molecular weight has been formed, the in situ made polyether polyol is removed from the reactor. These polyether polyols are particularly suitable for the production of flexible polyurethane foams.

  • Patent number: 8618014
    Abstract: Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

  • Publication number: 20130316164
    Abstract: Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized triblock copolymer resin and/or a diblock copolymer resin at least partially cured into gel particles into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form a cured gelatinous elastomer or gel, which is then reduced in size, for instance to give an average particle size of 10 millimeters or less. Polymerizing the polyol and the isocyanate forms polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to at least partially melt the styrene-portion of the triblock copolymer resin thereby extending the crosslinking and in some cases integrating the triblock copolymer within the polyurethane polymer matrix. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink.
