Patent ID: 8038725

Claim:
Hydrophilic polyolefin material comprising a polymeric mixture of at least one polyolefin and at least one melt additive containing a fatty acid ester of the general formula R—CO—O—CH 2 —CH 2 —O—R′, where R is a straight-chain or branched-chain alkyl residue with 23 to 35 carbon atoms, and where R′=H, —CH 3 , —C 2 H 5 , —C 3 H 7 , —C 4 H 9 , wherein the fatty acid is intermixed and dispersed in the polymeric mixture; and a composition of a silicone compound and a quaternary ammonium compound disposed on a surface of the polyolefin material, wherein fatty acids disposed in the polymeric mixture towards the surface of the polyolefin material are activated by applying the composition of a silicone compound and a quaternary ammonium compound to the surface of the polyolefin material.
