Popis:	In plasma treatments, the process gas is usually fed into the chamber in a more or less continuous way. The pulsing of the process gas can provide new opportunities. Some of them are explored in this paper. The interrupted or alternating process gas flux can help in mixing the sample in an activation treatment of a polyethylene powder. If the pores are not too small, a pressure pulse can help to improve the oxidation inside a porous polyolefin material. A plasma polymerization of ethene or allylamine can be more efficient if the timing of a plasma power pulse and the monomer pulse is optimized. Radicals are formed in the surface during the plasma pulse and these radicals initiate a polymerization of the monomer at a higher pressure.
