The present invention relates to a novel polymer as binder for producing activated carbon filters. The polymer of the invention is a polyethylene homopolymer and/or copolymer having a melt flow index (MFI 190/15) of from 1.2 g/10 min to 10 g/10 min, a polydispersity M/Mof from 3 to 30, a bulk density of from 0.05 g/cmto 0.5 g/cmand a particle size from 5 &#x3bc;m to 300 &#x3bc;m.

Activated carbon filter

The present invention relates to a novel polymer as binder for producing activated carbon filters. The polymer of the invention is a polyethylene homopolymer and/or copolymer having a melt flow index (MFI 190/15) of from 1.2 g/10 min to 10 g/10 min, a polydispersity M /M of from 3 to 30, a bulk density of from 0.05 g/cm to 0.5 g/cm and a particle size from 5 &mgr;m to 300 &mgr;m.

Hydrophilically modified high and/or ultra-high molecular weight polyethylene (HMW-PE or UHMW-PE) coated with a mixture comprising 1-99.9% by weight of at least one water-soluble additive and 0.1 to 99% by weight of at least one water-insoluble additive, the content of the mixture being 0.1 to 10% by weight, based on the total weight of hydrophilically modified HMW-PE and/or UHMW-PE and a process for the preparation of the hydrophilically modified HMW-PE and/or UHMW-PE and its use for the production of porous moldings.

Hydrophilically modified polyethylene resins

A graft copolymer based on ultrahigh-molecular-weight polyethylene having a molecular weight .gtoreq. 1,000,000 g/mol, an ethylene copolymer and a graft monomer; and the preparation and use thereof. The ethylene copolymer contains ethylene and vinyl acetate or ethylene and an alkenecarboxylic acid ester. The graft monomer is an alkenecarboxylic acid or an alkenecarboxylic anhydride. The resultant graft polymers posses improved properties compared with the materials from which they are derived.
