  • Process for the production of disulfides
    Patent number: 4990675
    Abstract: A process for the production of diorganodisulfides by oxidation of meraptans in which the mercaptan is reacted with a halogen compound capable of releasing at least one halogen atom and taking up a hydrogen atom instead, the reaction being carried out at 0.degree. to 100.degree. C. in the presence of base and, optionally, a phase transfer catalyst.
    Type: Grant
    Filed: April 12, 1989
    Date of Patent: February 5, 1991
    Assignee: Bayer Aktiengesellschaft
    Inventors: Michael Sauerbier, Karl Nutzel, Kurt Schilling
  • Process for crosslinking chlorinated polyethylene
    Patent number: 4551505
    Abstract: The crosslinking of chlorinated polyethylene with 2,5-dimercapto-1,3,4-thiadiazole in the presence of a basic substance may be carried out easily and leads to improved vulcanizate properties if amido amines, for example tetraethylene pentamine distearate, are used as the basic substances.
    Type: Grant
    Filed: September 25, 1984
    Date of Patent: November 5, 1985
    Assignee: Rhein-Chemie Rheinau GmbH
    Inventors: Michael Sauerbier, Helfried Ehrend
  • Use of cross-linked epoxidized fatty oils in vulcanizing polymers
    Patent number: 4524182
    Abstract: Epoxidized and subsequently cross-linked esters of alcohols which are at least dihydric and unsaturated fatty acids may be used as active processing substance in polymers, in particular elastomers, at higher temperatures, in particular at higher vulcanization temperatures, than "Factice". They may be produced by a particularly elegant one-shot reaction.
