Multistage process for producing low-temperature resistant polypropylene compositions |
| abstract |
A process for polymerizing propylene in the presence of a polymerization catalyst by copolymerizing propylene with a comonomer selected from the group of ethylene and C4-C10 alpha-olefins in three polymerization stages. The polymer produced in the first polymerization stage has the highest melt flow rate and the lowest content of comonomer. The polymer produced in the last polymerization stage has the lowest melt flow rate and the highest content of comonomer. The polymer composition produced by the process has good mechanical properties and can be used for making pipes. The process has a good productivity. |
