  • Publication number: 20230329239
    Abstract: A composition and method for killing feral hogs: a bait that is attractive to hogs is mixed with a lethal amount of sodium nitrite, along with sufficient base to inhibit decomposition of the sodium nitrite. At sufficiently high pH, encapsulation of the sodium nitrite is not required to inhibit decomposition. In the absence of substantial decomposition, the sodium nitrite itself is not aversive to the pigs, and may even enhance acceptance of the baits by the pigs. Optionally, an anti-emetic compound is added to the mixture to reduce the likelihood the bait will be vomited. Optionally, an additional toxicant such as luteolin is added to the mixture.

  • Publication number: 20150299412
    Abstract: Thiol-acrylate copolymers are disclosed that are useful, for example, as injectable biomaterials to provide both mechanical support and biological cues to stimulate bone regrowth. Composites can be formed, for example incorporating hydroxyapatite crystal inclusions into the copolymer. In one embodiment, the composite is gas-foamed with a blowing agent during or before cure to form a porous, interconnected scaffold. The synthesis employs an amine-catalyzed Michael addition co-polymerization of a poly-thiol with a poly-acrylate. The catalyst is an in situ catalyst, such as a tertiary amine moiety that is covalently bonded to one of the reactants, preferably to the poly-acrylate. The materials can rapidly co-polymerize in vivo or in vitro via catalysis by the “attached” in situ tertiary amine groups.

  • Publication number: 20090155485
    Abstract: The present invention provides a method for rapidly curing wood putty utilizing frontal polymerization. The reaction is initiated with UV light, and a reaction front propagates through the putty, completing the cure in seconds. A depth of cure of more than 1 cm deep of the wood putty is rapidly achieved.

  • Publication number: 20060142512
    Abstract: A polymerization composition is formed by mixing a monomer polymerizable by frontal polymerization and an encapsulated, free-radical initiator which can be released by the application of heat. In a second embodiment, the monomer is also encapsulated.

  • Patent number: 6313237
    Abstract: Functionally gradient polymeric materials are formed by a process that utilizes an ascending polymerization front. A polymerization front is initiated in a reaction vessel containing a monomer solution. Additional monomers or resins are added on top of the polymerization front to maintain a substantially constant level. The composition of the monomers and/or additives are varied as they are added to the reaction vessel to form a functionally gradient polymeric material.
