The present invention pertains to a stabilized hot melt adhesive containing a) one or more hot melt adhesive materials and b) a stabilizer composition. The one or more hot melt adhesive materials a) include a polyolefin, a styrene-isoprene-styrene block co-polymer, a styrene-butadiene-styrene block co-polymer, a polyacrylate, an acryl-copolymer, an ethylene vinyl acetate, a polyamide, a polyester, a polyurethane, a polyimide, a silane terminated polyolefin, a silane terminated poly-ether, and a silane terminated polyurethane. The stabilizer composition includes a component (B), which is a polymeric sterically hindered amine, and a component (C), which is a specific sterically hindered phenol.

Stabilization of hot melt adhesives

The present invention relates to a stabilizer composition containing at least one sterically hindered amine (HALS) in which the amino group carries a basicity-reducing substituent, at least one antioxidant containing one or more thioether groups and at least one liquid plasticizer containing carboxylate groups. The invention further relates to a polymer composition containing at least one sterically hindered amine (HALS) in which the amino group carries a basicity-reducing substituent, at least one antioxidant containing one or more thioether groups, at least one liquid plasticizer containing carboxylate groups and at least one silyl-terminated polymer, to the use of the stabilizer composition for stabilizing a silyl-terminated polymer or a sealant, adhesive, gasket, knifing filler or coating composition, especially a sealant, adhesive, gasket, knifing filler or coating composition containing a silyl-terminated polymer, against degradation by heat, light and/or oxygen, to the use of the polymer composition as or in a sealant, adhesive, liquid gasket, knifing filler or coating composition, and to a sealant composition or an adhesive composition, or a gasket composition, or a knifing filler composition or a coating composition comprising the polymer composition.

Stabilizer composition

The present invention pertains to a stabilized hot melt adhesive containing a) one or more hot melt adhesive materials and b) a stabilizer composition. The one or more hot melt adhesive materials a) include a polyolefin, a styrene-isoprene-styrene block co-polymer, a styrene-butadiene-styrene block co-polymer, a polyacrylate, an acryl-copolymer, an ethylene vinyl acetate, a polyamide, a polyester, a polyurethane, a polyimide, a silane terminated polyolefin, a silane terminated poly-ether, and a silane terminated polyurethane. The stabilizer composition includes two or three of a component (A) which is a specific sterically hindered amine, a component (B) which is a polymeric sterically hindered amine, and a component (C) which is a specific sterically hindered phenol.

Lubricating oil compositions comprise one or more polytetrahydrofuranes that are prepared by alkoxylating polytetrahydrofurane with at least one C8-C30 epoxy alkane.

Use of polytetrahydrofuranes in lubricating oil compositions

Provided are polyalkoxylates that are prepared by alkoxylating polytetrahydrofurane with butylene oxide for use in lubricant compositions and/or for reducing friction in a driveline.
