PRODUCTION OF TERPOLYMER
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 stages. CONSTITUTION:A terpolymer is produced by (A) feeding 92.0-98.0wt%...

| description | 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 stages. CONSTITUTION:A terpolymer is produced by (A) feeding 92.0-98.0wt% propylene, 2.0-5.0wt% ethylene and 0-3.0wt% butene-1 to a polymerization system and polymerizing 5-30wt% total monomers and, then, (B) feeding 85.0-92.0wt% propylene, 6.0-9.0wt% ethylene and 2.0-6.0wt% butene-1 to the polymerization system and polymerizing the remaining 95-70wt% monomers. Thus, it becomes possible to improve slurry properties, to heighten the productivity of the desired polymr, to carry out separation 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. |
