摘要

Two polyolefins: i) A polyolefin that contains about 80 to 150 branches per 1000 methylene groups. For every 100 methyl branches, there are about 30-90 ethyl branches, 4-20 propyl branches, 15-50 butyl branches, 3-15 amyl branches and 30-140 hexyl or longer branches. ii) A polyolefin, which contains about 20 to 150 branches per 1000 methylene groups. For every 100 methyl branches, there are about 4-20 ethyl branches, 1-12 propyl branches, 1-12 butyl branches, 1-10 amyl branches and 0-20 hexyl or longer branches. Also claimed is an ethylene homopolymer with a density of 0.86 g/ml or less, a polymer of one or more alpha-olefins of the formula CH2=CH2(CH2)aH which contains the above formula (XXV), wherein R35 is an alkyl group and R36 is an alkyl group containing two or more carbon atoms. In addition, a polypropylene containing one or both of the above formulas (XXVII) and (XXIX), provided that, if (XXIX) is present, it has to be in a greater than or equal amount to 0.5 of (XXIX) per 1000 methylene groups, or the polymer contains at least 0.5 or more of (XXVIII) per 1000 methylene groups.
