OLEFIN POLYMER COMPOSITION POWDER AND MODIFIED OLEFIN POLYMER

摘要

Disclosed is an olefin polymer composition powder having excellent powder properties which is useful as a raw material for a modified olefin polymer having high modification degree. Also disclosed is a modified olefin polymer having high modification degree obtained from such an olefin polymer composition powder. Specifically disclosed is an olefin polymer composition powder containing 100 parts by weight of an olefin polymer powder (A), 0.1-20 parts by weight of an ethylenically unsaturated bond-containing monomer (B), 0.1-20 parts by weight of an organic peroxide (C) and 0.1-20 parts by weight of an organic porous powder (D). Also specifically disclosed is a modified olefin polymer obtained by heating such a powder.
