Abstract: A method for fabricating a medical tubing comprising the steps of : a) providing a material selected from the group consisting of ethylene homopolymers and ethylene copolymers. The ethylene copolymers are obtained by copolymerizing ethylene with a comonomer selected from the group consisting of lower alkyl olefins, lower alkyl esters of a carboxylic acid and lower alkene esters of a carboxylic acid or blends thereof. b) providing an extruder with an extrusion die; c) extruding the material into a medical tubing; d) providing a surface modifier solution; e) preheating the surface modifier solution to a temperature within the range of 30-95 C; f) applying the preheated solution onto the tubing at it exits the extrusion die when the tubing is in a molten state or a semi-molten state.
