Abstract: The objectionable odor of one component condensation curable organopolysiloxane compositions is eliminated by replacing all or the most substantial part of water scavenger vinyltrimethoxysilane with a phenyltrialkoxysilane, without compromising storage or curing properties.

Abstract: RTV-1 compositions, despite containing conventional alkoxysilyl-terminated polymers, exhibit rapid cure and excellent physical properties when they further contain silicone resins, and employ metal, amidine, or guanidine curing catalysts C1 and amine-containing cocatalysts C2 in specific mole ratios.

Abstract: Moisture curable compositions having a low modulus and a high resilience are prepared by curing a composition containing a first polymer which predominately contains two moisture-curable silyl groups, and a second polymer which is terminated by an alkoxy group and contains but a single moisture-curable silyl group, or a hydroxyl group.

Abstract: Floor coatings with improved properties are prepared from alkoxysilyl-functional polymers, silicone resins with a high alkoxy group content, and a filler component, at least a portion of which contains large particle sizes.

Abstract: A process is provided for the production of linear saturated alkanes from one or more primary alcohols, wherein the carbon chain of the one or more primary alcohols has one carbon atom more than the alkane, including conducting reductive dehydroxymethylation of one or more primary fatty alcohols containing 8 to 24 carbon atoms, at a temperature ranging from 100 to 300° C. and pressures from 1 to 250 bar in the presence of hydrogen and a catalyst, and removing water formed during the reaction.

Abstract: Isocyanate-functional silanes are prepared in high yield by pyrolysis of an O-carbamate prepared by reaction of a dialkylcarbonate with an aminoalkyl-functional silane in the presence of a basic catalyst, where the catalyst is neutralized by an acid which has a pKa of all protolysis stages of not more than 4. The neutralized or partially neutralized catalyst need not be removed prior to pyrolysis. The isocyanato-functional silanes exhibit higher storage stability as compared to those prepared from O-carbamates where catalyst neutralization is effected by weak acids.

Abstract: Moisture curable compositions having a low modulus and a high resilience are prepared by curing a composition containing a first polymer which predominately contains two moisture-curable silyl groups, and a second polymer which is terminated by an alkoxy group and contains but a single moisture-curable silyl group, or a hydroxyl group.

Abstract: A composition containing an alkoxysilyl-functional polymer, a phenylsilicone resin, and a non-reactive plasticizer, when cured, exhibits very high elongation without loss of tensile strength. The compositions are particularly well suited for flexible adhesives.

Abstract: The objectionable odor of one component condensation curable organopolysiloxane compositions is eliminated by replacing all or the most substantial part of water scavenger vinyltrimethoxysilane with a phenyltrialkoxysilane, without compromising storage or curing properties.

Abstract: Moisture-curing adhesives simultaneously having high tensile strength and elongation are prepared by admixing a silane-terminated polyurethane or polyether polymer having a defined and limited molecular weight, finely divided silica, and an organosilicon compound containing basic nitrogen.

Abstract: RTV-1 compositions, despite containing conventional alkoxysilyl-terminated polymers, exhibit rapid cure and excellent physical properties when they further contain silicone resins, and employ metal, amidine, or guanidine curing catalysts C1 and amine-containing cocatalysts C2 in specific mole ratios.

Abstract: The invention relates to a catalyst for catalysing the polymerisation of epoxides, and which is to be improved such that it allows a more efficient reaction to be carried out. This is achieved by providing a catalyst obtainable by mixing a) at least one double metal cyanide compound, b) at least one organic complexing agent, and c) at least one primary alcohol with 6 to 24 C atoms. In addition, the invention relates to a method for the polymerisation of epoxides, and to the use of the claimed catalyst for the polymerisation of epoxides and the copolymerisation of epoxides with carbon dioxide.

Abstract: Adhesives having high tensile strength are prepared from moisture-curable alkoxysilyl-terminated polyurethanes.

Abstract: A crosslinkable composition comprising aminoalkyl-functional and epoxy-functional silanes and/or siloxanes provides an improvement in adhesion and sealing of various substrates under the conditions of cold-water storage, especially when a significant portion of all the silicon units has an amino-functional or an epoxy-functional unit and has an SiC-bonded, optionally halogen-substituted alkyl radical.
