## Abstract Structure and properties of presumed polypropylene(PP)‐b‐polyethylene(PE) block copolymers (PPPE) and the corresponding blends (PP/PE) have been investigated by wide‐angle x‐ray scattering (WAXS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), torsional pend
## Abstract Copolymers of ethylene and C^14^‐labeled propylene were prepared with a metal‐oxide catalyst which polymerizes ethylene to a high density polymer. Methyl branches arising from the propylene were counted radiochemically and then related to the infrared absorption of films at 8.7 μ. This
