description The present disclosure provides a process. In an embodiment, the process includes producing a propylene-based polymer in a gas-phase polymerization reactor (10) under polymerization conditions. The polymerization conditions include a combined propylene-plus-propane partial pressure from 290 psia to 450 psia. The process further includes maintaining the combined propylene-plus-propane partial pressure in the range from 290 psia to 450 psia while simultaneously: (i) reducing propylene partial pressure in the gas-phase polymerization reactor; (ii) adding propane to the gas-phase polymerization reactor; (iii) introducing at least one C4-C10 comonomer into the gas-phase polymerization reactor (26); and forming a propylene/C4-C10 interpolymer in the gas-phase polymerization reactor (44).
