Patent number: 5142082Abstract: Novel silane compounds, tert.-butoxy cyclopentyl dimethoxysilane and isopropoxy cyclopentyl dimethoxysilane, are prepared by reacting cyclopentyl trihalosilane with ROH (where R stands for tert.-butyl or isopropyl group) and then with methanol, or by reacting cyclopentyl trimethoxysilane with ROH. The silane compounds are useful as a catlaytic component for olefin polymerization and as a silane coupling agent.Type: GrantFiled: November 4, 1991Date of Patent: August 25, 1992Assignee: Tonen CorporationInventors: Ryuji Sato, Satoshi Ueki, Tomoko Aoki, Yoshiharu Okumura

Patent number: 4924022Abstract: Disclosed is a one reactor, continuous system for the manufacture of organoalkoxysilanes. The reactor consists of a fractionating means that allows for completion of the reaction and separation of the HCl formed as a by-product. Also disclosed is a means for removing or reducing any residual hydrolyzable chloride or other acids in the organoalkoxysilanes using ion exchange resins.Type: GrantFiled: October 4, 1989Date of Patent: May 8, 1990Assignee: Dow Corning CorporationInventors: Howard M. Bank, Robert A. Petrisko

Patent number: 4906721Abstract: Novel organopolysiloxanes are disclosed which comprise ##STR1## wherein R.sup.1 is methyl or phenyl, with the proviso that at least 90% of R.sup.1 is methyl; andR.sup.2 is(a) R.sup.1,(b) linear or branched alkinoxy with 3 to 25 carbon atoms, or(c) a polyalcohol with 2 to 6 hydroxyl groups from which the H-atom of the OH-groups is eliminated, with all but one of the OH-groups being etherified with allyl alcohol.The siloxanes must meet the conditions that at least one--C.tbd.C-- group is contained in the average molecule and that the numerical ratio of the --C.tbd.C-- group to the allyl ether groups is 5:1 to 1:250.The novel organopolysiloxanes, mixed with hydrogenpolysiloxanes and a catalyst, are stable at room temperatures and cure rapidly at elevated temperatures. The cured mixtures have adhesive properties and exhibit no malfunctions due to migration of portions not linked chemically. A process for preparing the organopolysiloxanes is also disclosed.Type: GrantFiled: April 20, 1988Date of Patent: March 6, 1990Assignee: Th. Goldschmidt AGInventors: Christian Weitemeyer, Goetz Koerner
