Syndiotactic Polypropylene 128B
Published: December 1995
This new type of polypropylene is highly crystalline and has very desirable properties, particularly clarity, room temperature impact strength, heat sealability, and controllable melting point.
As of early 1995, syndiotactic polypropylene (sPP) has been produced only in experimental quantities by Fina Oil and Chemical Company and Mitsui Toatsu.
This report reviews the technology for sPP production and examines the process economics of a conceptual bulk loop reactor process, a conceptual bulk slurry process, and a conceptual diluent slurry process. The study also reports the industry status of sPP, including properties of some laboratory and experimental products.
This report should be useful not only to present and future polypropylene producers but also to present and future producers of other polyolefins, such as low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), and to producers and users of other thermoplastics, such as polyvinyl chloride (PVC).
