Abstract

See full text

The invention relates to a film Film comprising a random graft copolymer having a polypropylene (PP) backbone and from 3 to 8 polyester segments covalently bonded to said backbone, wherein the number average molecular weight (Mn) of the polypropylene backbone ranges between 10.000 and 100.000 Dalton (as determined with HT-SEC in o-DCB at 150° C.), wherein the Mn of each polyester segment ranges between 5.000 and 25.000 Daltons, wherein the amount of PP ranges between 45 and 80 mol %, wherein the amount of polyester segments ranges between 55 and 20 mol %, wherein the film has a thickness in the range of 0.01-10 mm, wherein the polypropylene and polyester domains form independently continuous phases, and wherein the mol % is calculated relative to the total moles of monomer units present in the copolymer. The invention further relates to a nano porous PP membrane and its use.
