Abstract

A process for producing terpolymers of propylene, comprising a) feeding into a slurry reactor a reaction mixture containing 50-85 w- percent of propylene, 1-10 w- percent of ethylene, 15-40 w- percent of another C 4 -C 8 alpha-olefin, a catalyst system maintaining olefin polymerization at said temperature conditions, and optionally hydrogen, b) polymerizing said reaction mixture at a temperature of lower than 70 degrees centigrade a sufficient time to obtain a propylene terpolymer amounting to 50-99 w- percent of the end product, c) transferring said reaction mixture into a gas phase reactor operating at a pressure of higher than 5 bars, preferably higher than 10 bars, optionally adding 0-30 w- percent of ethylene, 0-10 w- percent of another C 4 -C 8 alpha-olefin, 0-40 w- percent of propylene and optionally hydrogen, and d) continuing polymerization in said gas phase reactor for obtaining a propylene terpolymer amounting to 1-50 wt- percent of the end product. The terpolymer has a melting temperature a less than 135 degrees centigrade, preferably less than 132 degrees centigrade, and it can be used for manufacturing films having good sealing properties.

N1 - Process for the production of propylene terpolymers

PY - 2005/12/30

N2 - A process for producing terpolymers of propylene, comprising a) feeding into a slurry reactor a reaction mixture containing 50-85 w- percent of propylene, 1-10 w- percent of ethylene, 15-40 w- percent of another C 4 -C 8 alpha-olefin, a catalyst system maintaining olefin polymerization at said temperature conditions, and optionally hydrogen, b) polymerizing said reaction mixture at a temperature of lower than 70 degrees centigrade a sufficient time to obtain a propylene terpolymer amounting to 50-99 w- percent of the end product, c) transferring said reaction mixture into a gas phase reactor operating at a pressure of higher than 5 bars, preferably higher than 10 bars, optionally adding 0-30 w- percent of ethylene, 0-10 w- percent of another C 4 -C 8 alpha-olefin, 0-40 w- percent of propylene and optionally hydrogen, and d) continuing polymerization in said gas phase reactor for obtaining a propylene terpolymer amounting to 1-50 wt- percent of the end product. The terpolymer has a melting temperature a less than 135 degrees centigrade, preferably less than 132 degrees centigrade, and it can be used for manufacturing films having good sealing properties.Patent family as of 14.2.20225Publication number Publication date Application number Application dateAR013126 AA 20001213 AR1998P103030 19980624AR016088 AA 20010620 AR1998P103031

AB - A process for producing terpolymers of propylene, comprising a) feeding into a slurry reactor a reaction mixture containing 50-85 w- percent of propylene, 1-10 w- percent of ethylene, 15-40 w- percent of another C 4 -C 8 alpha-olefin, a catalyst system maintaining olefin polymerization at said temperature conditions, and optionally hydrogen, b) polymerizing said reaction mixture at a temperature of lower than 70 degrees centigrade a sufficient time to obtain a propylene terpolymer amounting to 50-99 w- percent of the end product, c) transferring said reaction mixture into a gas phase reactor operating at a pressure of higher than 5 bars, preferably higher than 10 bars, optionally adding 0-30 w- percent of ethylene, 0-10 w- percent of another C 4 -C 8 alpha-olefin, 0-40 w- percent of propylene and optionally hydrogen, and d) continuing polymerization in said gas phase reactor for obtaining a propylene terpolymer amounting to 1-50 wt- percent of the end product. The terpolymer has a melting temperature a less than 135 degrees centigrade, preferably less than 132 degrees centigrade, and it can be used for manufacturing films having good sealing properties.Patent family as of 14.2.20225Publication number Publication date Application number Application dateAR013126 AA 20001213 AR1998P103030 19980624AR016088 AA 20010620 AR1998P103031
