The invention relates to the use of polyolefins modified with one or more silanes as adhesion promoters for the production of flat glass/glass, glass/plastic, or plastic/plastic laminates, to corresponding laminates, and to displays containing the laminates according to the invention.

Use of silane-modified polyolefins as adhesion promoters for the production flat laminates

The present invention relates to modified polyolefins having a propylene content of at least 50 ma-% and a maximum of 75 ma-%, being determined by means ofC-NMR spectroscopy, and having a poly(ethylene) triad content of a maximum of 2.5 ma-%, being determined by means ofC-NMR spectroscopy, relative to the total detected ethylene content, a melting heat of at least 9 and a maximum of 20 J/g, determined by means of differential calorimetry, and a solubility in xylol at ambient temperature of at least 96 ma-%, and a solubility in THF at ambient temperature of at least 67 ma-%, wherein one or multiple silanes are grafted onto the polymer. The invention further relates to a method for the production of the polyolefins, and to the use thereof, particularly in or as an adhesive.

Silane-modified polyolefins having a high degree of functionalization

A one-layer or multilayer sheet having good layer adhesion and good transparency is produced using a polyolefin which contains the following monomer units:

Use of a highly viscous largely amorphous polyolefin for the production of a film

A polyolefin which contains the following monomer units:

Highly viscous, largely amorphous polyolefin

Process for the preparation of substantially amorphous poly-&agr;-olefins

Reinforced molding material

Crosslinkable molding material

An adhesive bond is produced using an adhesive composition which comprises a silane-grafted, largely amorphous poly-.alpha.-olefin prepared by grafting onto said largely amorphous poly-.alpha.-olefin a silane compound having from 1-3 alkoxy groups attached directly to the silicon and at least one olefinic double bond containing moiety, and then crosslinking the adhesive composition by means of water.

Use of silane-grafted amorphous poly-.alpha.-olefins as

The process of the invention, using a plurality of passes, divides the crude product of each pass into a part which contains tetramers and higher oligomers and represents the desired product of a pass and at least one further part which contains the major part of the monomers, dimers and trimers and which serves at least in part as part of the starting materials in a subsequent reaction pass. At the same time, the catalyst concentration is increased. In all reaction passes, only a moderate starting material conversion is sought.

Process for preparing an oligomer mixture from

The invention relates to the use of polymethylalkanes having terminal methyl groups and methylene and ethylidene groups of the formula I ##STR1## in which the total number of C atoms n+2 m+2 is 20 to 100 and the ratio of the methyl and methylene groups to the ethylidene groups is 3 to 20:1 and the ethylidene groups are always separated by at least one methylene group, as biodegradable base oils for lubricants and functional fluids. Suitable polymethylalkanes are obtained by oligomerization of .alpha.,.omega.-diolefins, for example in particular according to P 41 19 332.6, or by pyrolysis of ethene/propane copolymers and subsequent hydrogenation in each case. The polymethylalkanes can be combined with conventional additives and other degradable or non-degradable base oils.

Use of polymethylalkanes as biodegradable base oils in lubricants and

A method of manufacturing methylidene-group-containing .alpha.,.omega.-unsaturated oligomers from .alpha.,.omega.-diolefins in the presence of a catalytic amount of organoaluminum compounds, wherein the .alpha.,.omega.-diolefins are reacted in the liquid phase, at 150.degree.-350.degree. C., and the organoaluminum compounds have formula AlX.sub.3 or AlX.sub.2 H, where X represents an aliphatic, alicyclic, or aromatic hydrocarbon group with 1-30 C atoms. The higher molecular weight hydrocarbons manufactured according to this method are substantially linear oligomers which contain reactive double bonds.
