1,214,485. Heterocyclic silicon compounds; chain-stopped polysiloxanes. GENERAL ELECTRIC CO. 6 Dec., 1967 [22 Dec., 1966], No. 55441/67. Headings C3S and C3T. The invention comprises heterocyclic silicon compounds of the general formula where R is a monovalent hydrocarbon or halohydrocarbon radical free of aliphatic unsaturation, R 1 is H or R and R 11 is an alkyleneoxyalkylene or alkylenethioalkylene radical. They can be prepared by contacting of a mixture of with a platinum catalyst. The compound of formula can also be prepared by the free radical addition of to The examples describe this preparation and the preparation of the compound These compounds are separately cohydrolysed with Me 2 SiCl 2 to give polydimethylsiloxanes terminated with respectively.
Abstract:
Addition curable organopolysiloxane compositions which are stable to premature gelation at room temperature for extended periods are provided. Said organopolysiloxane compositions comprise an olefinorganopolysiloxane, an organohydrogenpolysiloxane, a platinum catalyst, and a cure inhibiting amount of an ethylenically unsaturated isocyanurate.
Abstract:
A silicone compound of the formula, WHERE L is selected from secondary amine groups and R10 groups, R1 and R2 are selected from hydrocarbon groups and R3 and R4 are selected from hydrogen, hydrocarbon groups and other amine groups. Further, n is a whole number that varies from 1 to 20 and a is a whole number that varies from 0 to 2. These aminofunctional silane compounds may be used as sewage flocculents.
Abstract:
NEW COMPOSITIONS OF MATTER ARE PREPARED BY FORMING FUNCTIONAL SUBSTITUENTS ON THE SULFUR-ALKYL ESTER SIDE CHAIN OF A DITHIOCARBAMATE SUBSTITUENT FORMED ON AN ORGANOSILICON COMPOUND. THE NEW COMPOSITIONS ARE PREPARED BY REACTING AN ORGANOLSILICON COMPOUND, SUBSTITUTED WITH AN ALKYL AMINE, WITH CARBON DISULFIDE IN THE PRESENCE OF A TERTIARY AMINE AND REACTING THE REACTION PRODUCT WITH A COMPOUND HAVING A META-DIRECTING GROUP ATTACHED TO A CARBON ATOM HAVING AN OLEFINIC DOUBLE BOND.
Abstract:
THE PRESENT INVENTION RELATES TO CARBONYL-CONTAINING ORGANOSILICON MATERIALS USEFUL FOR MAKING ELASTOMERS HAVING IMPROVED RESISTANCE TO SWELL IN FLUID HYDROCARBONS. MORE PARTICULARLY, THE PRESENT INVENTION RELATES TO A METHOD OF ACYLATING AN ARYL NUCLEUS WITH CERTAIN CARBOXYLIC ACID HALIDES AND TO THE RESULTING SILICON CONTAINING MATERIALS OBTAINED THEREFROM.
Abstract:
A QUATERNARY AMMONIUM HYDROXIDE TYPE OF ION EXCHANGE RESIN IS USED IN A CYANOETHYLATION TYPE REACTION BETWEEN A BRANCHED CHAIN OLEFINIC NITRILE AND AN UNSATURATED ALCOHOL. THE CYANO(BRANCHED ALKOXY)ALKENE PRODUCED IS THEN REACTED WITH A SILANE BY AN SIH-OLEFIN ADDITION REACTION. THE CORRESPONDING AMINE IS MADE FROM THE NITRILE BY HYDROGENATION AT LOW PRESSURE. ONE OF THE SILANES PRODUCED BY THE ABOVE METHOD, 3-(2-METHYL-3-AMINOPROPOXY)PROPYLTRIMETHOXYSILANE, IS AN EXCEPTIONALLY VALUABLE COMPONENT IN DETERGENT RESISTANT POLISHES.
Abstract:
ORGANOPOLYSILOXANE COPOLYMERS ARE PREPARED BY THE PARTIAL HYDROLYSIS AND CONDENSATION OF A SILANOL CHAINSTOPPED POLYDIORGANOSILOXANE, AN AMINOALKYLTRIALKOXYSILANE, AND AN AMINOALKOXYALKYLTRIALKOXYSILANE. THESE COPOLYMERS ARE CONVERTED TO PARTIAL SALTS BY REACTION WITH WITH ALIPHATIC CARBOXYLIC ACIDS AND THE PARTIAL SALTS ARE USED IN DETERGENT RESISTANT POLISH FORMULATIONS OF IMPROVED RUB-OUT AND GLOSS.
Abstract:
A METHOD FOR PREPARING MERCAPTOALKYL ORGANOSILANES, HAVING A RANGE OF SUBSTITUENTS OTHER THAN THE MERCAPTOALKYL GROUP, EMPLOYING THE ADDITION OF A SILICON HYDRIDE GROUP ACROSS THE DOUBLE BOND OF AN OLEFINICALLY UNSATURATED COMPOUND.
