  3. 제2항에 있어서, 조성물을 표면제로 피복시킨 방법.
  4. 제1항에 있어서, 탈활성화시키려는 촉매가 지글러-나타형 촉매인 방법.
  5. 제1항에 있어서, 반응기 시스템의 마지막 지점에서 혹은 반응기시스템 바로 후에 촉매탈활성화제를 반응혼합물중에서 주입시키는 방법.
  6. 제1항에 있어서, 에틸렌 혹은 에틸렌과 3 내지 10개의 탄소원자를 가지는 하나 이상의 α-올레핀의 혼합물을 중합시키는 방법.
  7. 제6항에 있어서, 에틸렌 혹은 에틸렌과 부텐-1, 헥센-1 혹은 옥텐-1중의 적어도 하나와의 혼합물을 중합시키고 촉매가 티타늄을 함유하는 방법.
