  • Patent number: 8519059
    Abstract: The invention provides articles obtained from curing a composition consisting of a polymercapto crosslinking agent, a vulcanization accelerator, an inorganic base, a nitrogen containing chelating agent, wherein the nitrogen containing chelating agent is selected from the group consisting of 1,10-phenanthroline and 2,2-bipyridyl, and polyethylenimine; and a halogenated elastomer; wherein said nitrogen containing chelating agent is soluble in said halogenated elastomer.

  • Patent number: 8399572
    Abstract: The invention provides compositions comprising nitrogen containing chelating agents, which can be used to reduce the effects of zinc contamination on the vulcanization rates of polymercapto based cure systems for halogenated elastomers. Such chelating agents are effective at eliminating vulcanization rate inconsistencies due to zinc contamination, without inducing negative changes to the vulcanization reaction or the subsequent physical properties of the halogenated elastomer vulcanizate. The invention also provides methods of curing a halogenated elastomer using the inventive compositions, and for articles prepared from the same.

  • Publication number: 20120104189
    Abstract: A hands-free baby bottle holder for holding a baby bottle in various positions comfortable for feeding a baby comprising a sleeve which can be removably wrapped around a baby bottle and which secures to itself via at least one fastening device. Four rings are coupled to the sleeve. Two of the four rings are coupled to the top of the sleeve and the remaining two of the four rings are coupled to the bottom of the sleeve. Four removable and adjustable cords are each connected to one of the four rings via a securing device situated at the first end of each of the four removable and adjustable cords. Each of the second ends of the four removable and adjustable cords is attached to clothing or around handle bars on strollers, car seats and the like via a clipping device so as to hold the bottle in a position comfortable for feeding a baby.
