• Application of ambient temperature cured polymers of prepolymers to a cured elastomer

  公开号：EP0123070A2

  公开（公告）日：1984-10-31

  A process and composition for applying and bonding an amine curable polymer or prepolymer at ambient temperatures to the surface of a cured elastomer substrate. The elastomer article or substrate is treated with an organic oxidant such as an N-halohydantoin, N-haloamide, or an N-haioimide, for example, the various isomers of mono-, di-, and trichloroisocyanuric acid. A polyisocyanate is applied thereto. A composition of the amine curable polymer or prepolymer is prepared with an amine curing agent. To the curing agent and curable polymer or prepolymer composition is added a polar solvent which is mixed with the resulting blend or mixture and added to the treated elastomer surface; said polymer or prepolymer cures at ambient temperature and becomes bonded to said elastomer. The application is relatively easy, since the entire mixture is a liquid and can be applied in situ. The invention is particularly suitable for repairing various damaged elastomer articles such as tires (especially off-the-road), conveyor belts, hoses, preparation of caulking or sealing compounds, and especially in bonding tire lugs or tire treads to a tire carcass.

  一种在环境温度下将胺固化聚合物或预聚物涂抹和粘合到固化弹性体基材表面的工艺和组合物。用有机氧化剂，如 N-卤代海因、N-卤代酰胺或 N-卤代亚胺，例如一氯、二氯和三氯异氰尿酸的各种异构体，处理弹性体制品或基材。多异氰酸酯用于其中。用胺固化剂制备胺固化聚合物或预聚物的组合物。在固化剂和可固化聚合物或预聚物组合物中加入极性溶剂，将其与所得混合物或混合料混合并加入处理过的弹性体表面；所述聚合物或预聚物在环境温度下固化并与所述弹性体粘合。由于整个混合物都是液体，可以就地使用，因此使用起来相对容易。本发明特别适用于修复各种受损的弹性体，如轮胎（尤其是越野轮胎）、传送带、软管，制备填缝剂或密封化合物，尤其适用于将胎耳或胎面粘合到轮胎胎体上。
• Process for the preparation of dl-beta-aryl amino acids
  申请人：ALKALOIDA VEGYESZETI GYAR

  公开号：EP0156582A1

  公开（公告）日：1985-10-02

  The invention relates to a process for the preparation of DL-β-aryl-amino acids of the general Formula. wherein R,R, and R2 stand for hydrogen, halogen, C1-6 alkyl, C1-6 alkoxy, nitro or C1-4 dialkylamino. An aqueous solution of glycine and an excess of urea is heated and the reaction mixture is subjected to acidic cyclisation. The hydantoin thus obtained is reached with an aromatic aldehyde of the general Formula in aqueous solution in the presence of an excess of ethanolamine or morpholine. The 5-arylidene hydantoin derivative of the general Formula thus obtained is reduced quantitatively in a dilute alkaline medium with a Raney-nickel or a palladium-carbon catalyst to yield the corresponding 5-aryl-methyl-hydantoin derivative of the general Formula R which is subjected to alkaline hydrolysis. The corresponding DL-β-aryl amino acid of the general Formula V is obtained in high yield and may be isolated at the isoelectric point thereof

  本发明涉及一种通式为 DL-β-芳基氨基酸的制备工艺。 其中 R、R和R2代表氢、卤素、C1-6烷基、C1-6烷氧基、硝基或C1-4二烷基氨基。 加热甘氨酸和过量脲的水溶液，并对反应混合物进行酸性环化。将得到的海因与通式为 在过量乙醇胺或吗啉存在的水溶液中进行反应。通式中的 5-芳基海因衍生物 在稀碱性介质中用雷尼-镍或钯-碳催化剂进行定量还原，生成相应的通式 R 的 5-芳基-甲基海因衍生物。 进行碱性水解。相应的通式 V 的 DL-β-芳基氨基酸的产率很高，并可在其等电点处分离出来。
