Disclosed herein are ethylene homopolymers generally characterized by a density of less than 0.94 g/cmand an inverse short chain branch distribution. These homopolymers can be further characterized by a ratio of Mw/Mn from 2 to 100, a number of short chain branches from 2 to 20 short chain branches per 1000 total carbon atoms, and wherein at least 50% of the short chain branches are methyl branches.

Ethylene homopolymers with a reverse short chain branch distribution

Disclosed herein is a process for forming an oligomer product comprising (a) introducing into a reaction zone (i) ethylene; (ii) a heteroatomic ligand metal salt complex comprising a heteroatomic ligand complexed to a first metal salt; (iii) a second metal salt wherein an equivalent molar ratio of the second metal salt to the heteroatomic ligand of the heteroatomic ligand metal salt complex is at least 0.5:1 and where the second metal salt is an iron salt, a cobalt salt, or any combination thereof; (iv) an organoaluminum compound; and (b) forming an oligomer product. Also disclosed herein is a process comprising (a) introducing into a reaction zone (i) ethylene; (ii) a heteroatomic ligand; (iii) a metal salt where an equivalent molar ratio of the metal salt to the heteroatomic ligand is at least 1.5:1; (iv) an organoaluminum compound; and (b) forming an oligomer product.
