    Abstract: The invention concerns a method of producing multi-phase block copolymers, the method being characterized in that, in the gas phase, in the presence of a metalocene catalyst system at temperatures of -50 to +300 DEG C and pressures of 1 to 1000 bar: a) as a first step, 45 to 95 % by wt. of a polymer matrix (A) comprising an alk-1-ene homopolymer or copolymer with a comonomer content of up to 10 % by wt. relative to the matrix (A) is produced and b) as a second step, in the presence of the matrix (A) obtained in step (a), b1) o.5 to 97 % by wt. of at least one alk-1-ene having at least 3 C-atoms and b2) 3 to 99.5 % by wt. of ethylene is reacted to give 5 to 55 % by wt. of a copolymer phase (B).
