Licensees of the UNIPOL Polypropylene Technology have access to more classes of products, and grades within those classes, than is available from any other commercial technology.

The ability to produce a wide range of polypropylene resins must be a key consideration as you evaluate the process technology you will choose. Experienced resin producers have identifi ed three important product-related questions to ask when comparing the various technologies:

What is the breadth and depth of the product offerings?

Does the process offer fl exibility to allow easy and economical changes in the product mix being produced?

Does the process have favorable economics across the entire product range?

The simplicity of the UNIPOL Polypropylene Technology offers several additional benefi ts because competitive technologies require additional processes and components.

Other processes require some or all of these:

Multiple processes to coordinate and control – as many as three in a series

Multiple reactors needed for large capacities or advanced products – as many as fi ve in a series

Pre-polymerization and/or catalyst pretreatment

Additional purifi cation

Stirrers or scrapers in the reactors

Solid separation equipment

Vent dryer recovery

Membrane separation unit for reactor vent gases

Intermediate storage and conveying

The simplicity of the homopolymer/random copolymer system is mirrored in the impact copolymer stage, which operates with the same gas phase fl uidized bed process in a slightly smaller reactor. For each reaction stage there are just three main pieces of equipment: the reactor, the cycle gas compressor and the cycle gas cooler.

With active catalyst entering from the fi rst stage, there is no need for additional catalyst feed to the impact reactor. The critical rubber component is polymerized directly in the growing polypropylene particles, achieving optimum rubber dispersion and morphology that results in the highest impact performance.
