Amorphous olefin co/ter-polymers

Polyphenylene ether blends and a process for the preparation thereof

The invention relates to a polymer for release films of surfaces containing pressure-sensitive adhesives. The polymer includes a reactive polyolefin and a reactive release substance, which are chemically bonded together as a result of being compounded in a molten state. The invention also relates to a release film for surfaces containing pressure-sensitive adhesives.

Melt-processable block copolyesterimide and method for manufacturing it

The invention relates to a thermoplastic elastomer composition comprising a) a polyolefin and b) a crosslinked ethylene copolymer, the crosslinks between the main chains of the molecules of which have been formed of the hetero groups of at least two comonomer units being in different main chains and at least two hetero groups of the crosslinking-agent molecule being chemically attached to each other. The problem of such a mixture is that the lipophilic thermoplastic polyolefin and the ethylene copolymer to be crosslinked with its polar hetero groups are not compatible. Now, the problem has been solved by forming the crosslinks between the main chains so that either the hetero group of the comonomer unit in the main chain or then the hetero group of the crosslinking agent molecule always is a hydroxyl group, the hydroxyl group always forming a permanent oxygen crosslink bond with the other hetero group attached to it.

Dynamically crosslinked polyolefin composition

The invention concerns a plastic coated steel tube which contains at least one layer of a polyolefin which has been modified with a hydrolyzable silane, and also a method for preparing this tube.

Modified polyolefin comprising a polyolefin linked to a hydrolyzable silane which is reactable with polyvinyl alcohol and being chemically bound to polyvinyl alcohol by the silane, and method for preparing the same.

Modified polyolefin, method for making the same, and use thereof

The present invention relates to a modified polyolefine which has good adhesion to metals and to polar substances. The polyolefine is admixed with or grafted to fumaric acid. The fumaric acid may be added at about 0.01-20%, preferably 0.01-1% of the polyolefine weight, while the preferred polyolefine is an ethylene copolymer.

Modified polyolefine

The present invention relates to a chemically modified polyolefin exhibiting good adhesion to metals and other polar substances. The polyolefin has itaconic acid grafted thereto.
