Abstract

PURPOSE: To obtain a terpolymer having good slurry properties during its copolymerization and a low heat-sealing temperature, by polymerizing propylene, ethylene and butene-1 in two stages at a specified monomer ratio for each stage.
CONSTITUTION: A terpolymer is produced by (A) feeding 88.0W97.0wt% propylene, 0W2.0wt% ethylene and 3.0W10.0wt% butene-1 to a polymerization system and polymerizing 5W30wt% of the total monomers and, then, (B) feeding 85.0W 92.0wt% propylene, 6.0W9.0wt% ethylene and 2.0W6.0wt% butene-1 to the polymerization system and polymerizing the remaining 95W70wt% of the monomers. Thus, it becomes possible to improve slurry properties, to heighten the productivity of the desired polymer, to carry out sparation readily and to obtain good heat- sealability by carrying out the polymerization reaction in two stages (A) and (B) and maintaining the ratio among propylene, ethylene and butene-1 fed to the polymerization system in each stage within the specified range.
