Patents by Inventor Cathryn E. Olsen

Cathryn E. Olsen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Silyl carbamates and their use in the preparation of bis (aminoalkyl) disiloxanes
    Patent number: 4631346
    Abstract: Silyl carbamates are prepared by reacting carbon dioxide with a silazane composition such as 2-methyl-2-sila-3-aza-5-hexene. The silyl carbamates may be converted to symmetrical bis(aminoalkyl)disiloxanes by hydrosilation followed by hydrolysis.
    Type: Grant
    Filed: August 22, 1985
    Date of Patent: December 23, 1986
    Assignee: General Electric Company
    Inventors: Jimmy L. Webb, Cathryn E. Olsen
  • Bis(aminoalkyl)disiloxanes and method and intermediates for their preparation
    Patent number: 4584393
    Abstract: Bis(aminoalkyl)disiloxanes such as 1,9-diamino-4,4,6,6-tetramethyl-5-oxa-4,6-disilanonane are prepared by contacting an acyclic olefinic silazane such as 2-methyl-2-sila-3-aza-5-hexene with a hydrosilation catalyst to form an intermediate which is then hydrolyzed. When certain olefinic silazanes are hydrosilated with a reaction product of a platinum compound with an olefinic siloxane, the intermediate is a composition comprising novel cyclic silazanes such as 1,1-dimethyl-1-sila-2-azacyclopentane.

  • Method for preparing olefinic silazanes
    Patent number: 4565885
    Abstract: Olefinic silazanes are prepared by the reaction of an olefinic amine such as allylamine with a silazane such as dimethylaminodimethylsilane or tetramethyldisilazane, preferably in the presence of a catalytic amount of a hydrogen halide source such as dimethylchlorosilane as catalyst. The highly volatile amino compound generated as a by-product (e.g., ammonia or dimethylamine) is lost by volatilization and this furnishes at least part of the driving force for the reaction.
