    摘要: A stabilized adhesive composition is provided including one or more polymerizable cyanoacrylate monomers, a first free radical stabilizer in a stabilization effective amount, and a second free radical stabilizer in a stabilization effective amount. The free radical stabilizers are selected to minimize mutagenicity in the composition and are used in amounts which provide adequate stabilization for long term storage while reducing disadvantageous effects of the free radical stabilizers. The stabilized adhesive composition further may include a first anionic stabilizer comprising a vapor phase anionic stabilizer and a second anionic stabilizer comprising a liquid phase anionic stabilizer. The stabilized adhesive composition may also include or be used with a polymerization initiator. Methods for the application of the stabilized adhesive compositions to living tissue are also provided.

    摘要: Disclosed is the observation that 7-aryl-quinone methides and 4-tert-butylcatechol, when used in combination in a vinyl aromatic monomer to inhibit polymerization,do not inhibit polymerization to the same extend as each would if used separately. Stated another way, a phenomenon has been observed that when these two compounds are used together, they can, to a large extent, render each other unable to inhibit polymerization in a vinyl aromatic monomer. Also disclosed are methods of preventing adverse results of this interaction when undesired and a method of using this interaction to prepare a reactive vinyl aromatic monomer having a concentration of 4-tert-butylcatechol that would otherwise inhibit polymerization. The invention is disclosed to be useful with the production and storage of any vinyl aromatic monomer and is disclosed to be particularly useful with the production and storage of styrene monomer.

    摘要: Toughened vinyl aromatic compounds, in particular high impact polystyrene, are prepared by a continuous process in which the vinyl aromatic compound and the impact modifier, an elastomeric block copolymer, are each prepared separately in a reaction zone by anionic polymerization, with or without heat exchange with the environment and, if required, with the addition of a solvent, and are polymerized until complete conversion is achieved, and the living chain ends are terminated in a manner known per se, and a thermoplastic, toughened molding material is based on a vinyl aromatic compound having a residual content of less than 50 ppm of monomers and less than 100 ppm of oligomers.
