Abstract
The invention provides compositions, each comprising an ethylene/alpha-olefin interpolymer, which has a reduced level of a low density, low molecular weight oligomeric fraction, as indicated by an HCC value, as described herein, and reduced levels of inorganic content or lower Tm. The invention also provides processes for forming such interpolymers.
