摘要：
A propylene polymer having specified relationships between a melt index and a molecular weight distribution and also between a melt tension and a limiting viscosity which is in a specified range and also having a long chain branch. It has properties equivalent or superior to those of conventional propylene polymers, and is excellent in melt processability and particularly suitable for blow molding or extrusion foam molding to give large-sized moldings. The polymer is suitable for use as a compatibilizer for a propylene homopolymer with a propylene copolymer.
