  • Publication number: 20140121399
    Abstract: The polymerization of monomers may be at least partially reduced or inhibited by introducing an effective amount of an additive. The additive may be or include a first compound: where: R1 and R2 may be or include an alkyl group, an aryl group, an alkyl group having a heteroatom, an aryl group having a heteroatom, and combinations thereof. The hetero atom may be or include sulfur, nitrogen and/or oxygen. R1 may be the same or different from R2. The polymerizable monomers may be or include, but are not limited to styrene, butadiene, isoprene, acrylic acid, acrylonitrile, vinyl acetate, and combinations thereof.

  • Patent number: 6512023
    Abstract: An adhesive composition includes a polymerizable adhesive monomer, at least one vapor phase stabilizer, and at least one liquid phase stabilizer. The combination of at least one vapor phase stabilizer and at least one liquid phase stabilizer provides superior stabilization and shelf-life for the monomer composition. The stabilized adhesive composition provides superior performance and shelf-life and can be sterilized without significant polymerization of the monomer.
