    • Certain specific embodiments of the invention will now be discussed. For example, a process of preparing a polymer composition that includes a branched crystalline diene-modified polypropylene random terpolymer is described, which process includes: contacting a metallocene catalyst compound with a polymerization medium that includes at least a propylene monomer, a first diene monomer, and a second diene monomer; and conducting polymerization of the monomers in the presence of the metallocene catalyst compound for a time sufficient to provide a branched crystalline diene-modified polypropylene random terpolymer that includes monomeric units derived from each of the monomers, and having from 0.0 wt % to 2.0 wt % ethylene and a heat of fusion of 30 J/g or more.
    • 现在将讨论本发明的某些具体实施方案。 例如,描述了制备包含支链结晶二烯改性的聚丙烯无规三元共聚物的聚合物组合物的方法,该方法包括:使茂金属催化剂化合物与至少包含丙烯单体,第一二烯单体, 和第二二烯单体; 并在茂金属催化剂化合物的存在下进行单体的聚合反应足以提供包含衍生自各单体的单体单元的支化结晶二烯改性的聚丙烯无规三元共聚物,并且具有0.0重量%至2.0重量% 乙烯和30J / g以上的熔融热。
