    Abstract: 3 - Allyloxymethyl - 3 - ethyl oxetane is prepared by converting the monallylether of trimethylol propane to its monosulphate ester and reacting this with sodium hydroxide (see Example 1). 3 - Allyloxymethyl - 3 - chloromethyl oxetane and 3,3-bis-(allyloxymethyl) oxetane are prepared by reacting sodium allyloxide with 3,3-bis-(chloromethyl oxetane) (see Example 4).ALSO:The invention comprises silanes and siloxanes of formula with or without units of formula wherein R is a divalent saturated aliphatic radical consisting of hydrogen, carbon, and optionally, oxygen, any oxygen in R being present as hydroxy, ether or ester linkages, and R being bonded to the silicon atom through a carbon-silicon bond; R1 is a hydrogen, hydrocarbon, halohydrocarbon, a radical containing an ether linkage, hydroxyalkyl or carboxyalkyl radical; R11 is a hydrocarbon, halohydrocarbon, hydrocarbonoxy or acyloxy radical and is free from aliphatic unsaturation; and a is 0-3. These compounds may be prepared by the condensation of (a) and in the presence of platinum to yield (b) and to yield and to yield or and to yield Siloxanes may also be prepared by the hydrolysis of the corresponding oxetane-containing silanes. The compounds may be cured, e.g. by reaction with BF3 or other Lewis acid. Many examples are given; typical examples describe the preparation of (1) (7) which was hydrolysed to a siloxane of unit formula and (9a) a siloxane copolymer comprising units of formulae CH3SiO 3/2 , (CH3)2SiO, C6H5SiO 3/2 and Uses.-Protective coatings, treating glass cloth for laminates, preparing silicone modified polyether rubbers, mouldings and films

    Abstract: The invention comprises organosilicon compounds, which cure on exposure to moisture, of the formula wherein a is 2-4, b is 0-1, R is a divalent radical free from aliphatic unsaturation, consisting of hydrocarbon radicals or radicals containing C, H and O and/or S in the form of ­C-O-C­, -OH, -SH or ­C-S-C­, c is at least 1, R1 is a multivalent hydrocarbon radical or a radical containing C, H and O in the form of ­C-O-C­ or ­C-OH, there being no acetylenic unsaturation in R1, R11 is a monovalent hydrocarbon radical or a halohydrocarbon radical, n is 0-2, X is a hydrolysable group or atom, m is one less than the valency of R1; there being an average of at least 2 Si atoms and 3X groups in each molecule. The preferred value of C is 5-100. X is preferably acyloxy, alkoxy or hydrocarbyl-substituted isocyanoxy. The compounds may be prepared (I) by reacting polysulphide polymers of the formula HS[CH2(R)bCH2Sa]cCH2(R)b CH2SH with a silane containing a substituent having the C=C group in the presence of peroxides or an alkaline catalyst, (2) by reacting the sodium salt of the polysulphide polymer with a silane having a halogen atom on an organic substituent, (3) by reacting a polysulphide polymer with an epoxy silane. The compounds may be stored without curing if they are kept anhydrous, even in the presence of curing catalysts. The compounds are cured on contact with water, preferably in the presence of catalysts such as alkyl titanates, metal salts of carboxylic acids, amines, amine salts of carboxylic acids and quaternary ammonium compounds. "Pigment," including structural fillers and extending fillers, may be added to the polymers, e.g. carbon blacks, silicas, TiO2, ZnO, lithopone and clay.

    Abstract: ORGANOSILICON COMPOUNDS HAVING THE SUBSTITUENT GROUP

    *SI-R-NH-(R1-NH)N-H

    WHERE N IS AT LEAST 14, ARE MADE BY REACTING $SIRCI WITH

    H-(NH-R1)N-NH2

    FOR EXAMPLE,

    (CH3-O-)3-SI-(CH2)3-CL + H-(NH-CH2-CH2)30-NH2 -->

    (CH3-O-)3-SI-(CH2)3-NH-(CH2-CH2-NH)30-H . HCL

    THE ORGANOSILICON COMPOUNDS INCREASE THE ADHESION OF POLYPROPYLENE AND OTHER PLASTICS TO GLASS AND GLASS FIBERS. ORGANOSILICON COMPOUNDS HAVING AMINO SUBSTITUENTS ON CARBON SIDE CHANS HAVE OBTAINED CONSIDERABLE COMMERCIAL SUCCESS. THESE INCLUDE SILANES HAVING THE AMINOPROPYL GROUP SUBSTITUTED ON SILICON AS WELL AS THOSE HAVING THE AMINOETHYLAMINOPROPYL GROUP. SUCH SILANES HAVE BEEN EMPLOYED IN MANY APPLICATIONS, INCLUDING THOSE RELATING TO THE PRIMING OF SURFACES TO INCREASE THE RECEPTIVITY OF DYES AND OF ORGANIC PLASTICS. U.S. PATS. 3,249,535 AND 3,317,577 SHOW ORGANOSILICON COMPOUNDS HAVING POLYIMINE GROUPS ATTACHED TO THE SILICON IN WHICH THE NUMBER OF IMINE UNITS RANGE UP TO ABOUT 10. IT HAS BEEN FOUND THAT THE COMPOSITIONS CLAIMED HEREIN GIVE IMPROVED ADHESION OF CERTAIN PLASTICE TO GLASS AND ARE IN OTHER WAYS SUPERIOR TO HERETOFORE KNOWN AMINOSILICON COMPLOUNDS AND THE HERETOFORE KNOWN POLYIMINO SILICON COMPOUNDS.
