The present invention relates to a blend containing at least two different polyolefins which is characterized in that it contains as a further constituent an amorphous poly-alpha-olefin which is based on the monomers ethene, propene and 1-butene and has a viscosity at 190° C. of 200 mPa*s to 200,000 mPa*s, wherein it contains polyethylene and polypropylene as at least two different polyolefins and wherein the polyethylene has a melt flow index [MFI 2.16 kg@190° C.] determined according to the method ISO 1133 reported in the description of less than 10 g/10 min, preferably of 0.01 to 2 g/10 min, and the polypropylene has a melt flow index [MFI 2.16 kg@230° C.] determined according to the method reported in the description of less than 50 g/10 min, preferably of 0.01 to 25 g/10 min, to a process for producing such blends and to the use thereof.

Amorphous polyalphaolefin-containing polyolefin blend

The invention relates to amorphous poly-alpha-olefins, which are characterized in that said amorphous poly-alpha-olefins have a viscosity at 190° C. of less than 5000 mPas, a molar mass distribution (Mw/Mn) of 3 to 8, a quotient Mz/Mw of less than or equal to 3.0 and a quotient Mz/Mn of less than 21.0. The invention further relates to a method for producing degraded amorphous poly-alpha-olefins, in particular the amorphous poly-alpha-olefins according to the invention, and to the use of the amorphous polyalpha-olefins according to the invention or produced according to the invention in hot-melt adhesive compositions.

Amorphous poly-alpha-olefins and use thereof in hot-melt compositions having improved sprayability

Acrylate-olefin copolymers and a method for the preparation of these copolymers are provided. Lubricant compositions can contain the aforementioned copolymers. The copolymers are useful as a lubricant additive or a synthetic base fluid in a lubricating oil composition, preferably in a gear oil composition, a transmission oil composition, a hydraulic oil composition, an engine oil composition, a marine oil composition, an industrial lubricating oil composition or in grease.
