Abstract

Homogeneous, random interpolymers of ethylene and lesser amounts by weight of olefinically-unsaturated comonomers are prepared in a substantially constant environment, substantially steady-state reaction mixture, in a well-stirred autoclave reactor, in continuous single-phase operation, using elevated synthesis conditions wherein the temperature and pressure are elevated to an amount high enough to approach, reach, or surpass the molecular weight distribution boundary.
