Abstract
A propylene polymer is excellent in rigidity, heat resistance, surface hardness, glossiness, transparency and impact resistance. A propylene copolymer (wherein the amount of monomer units derived from an .alpha.-olefin other than propylene is not more than 5% by mol) is excellent in transparency, rigidity, surface hardness, heat resistance, heat-sealing property, anti-blocking property, anti-bleedout property and impact strength. A propylene copolymer (wherein the amount of monomer units derived from an .alpha.-olefin other than propylene is not less than 5% by mol) is excellent in transparency, environmental aging property, and effective in improving heat-sealing property at low temperature and impact strength. A propylene elastomer is excellent in heat resistance, impact absorbing capacity, transparency, heat-sealing properties and anti-blocking properties.
