...ation and from crystallisation and physical models, which can be found in [3-5]. Dynamic Shear Modulus as a Function of Undercooling To investigate the viscoelastic behaviour of the undercooled melt of a metallocene-catalysed polypropylene (grade: Metocene X 50182, manufacturer: Basell), the storage (G') and loss (G'') components of the complex dynamic shear modulus (G*) as functions of undercooling were measured with the rotary rheometer (grade: Ares, manufacturer: Rheometric Scie...

...l new applications. Whether transparent, tinted or in solid colours, the aesthetic properties of Clyrell resins provide more design freedom and opportunity for product differentiation. However, one of the most promising developments is Basell's Metocene family of resins that feature advanced, propylene-based materials, produced with metallocene single-site catalysts. Based on one type of polymer molecule, Metocene resins are characterized by extremely narrow molecular weight and molecular we...

...advantages in terms of dimensional stability and warpage. The marketing of metallocene PP continues to remain clearly behind the original expectations. Only a fraction of one percent of the global market volume – essentially Basell’s Metocene and Exxon’s Achieve product families – comes from these catalysts. Polymer development in this field is also showing very little progress. Apart from homopolymers (with melt temperatures which are still distinctly inferior to those of ZN products) commercia...

...to avoid renewed tests on the product in the event of changes to the material. Other producers are offering a similar product series. Metallocene-based Polypropylene In addition to this, producers such as Basell, with its Metocene product series, are endeavoring to highlight PP products that are based on metallocene. Their narrow molecular mass distribution means they are characterized by an extreme purity, improved dimensional stability and a particularly high transparency. In addition, they ...

...range between 400 and 3,000 ml/10 min) is also desirable to improve the processing efficiency. This makes particular demands on the purity of the polymers. Grades are required with a low content of volatile oligomers. Metallocene grades, such as Metocene MF650Y (manufacturer: LyondellBasell) characterized by good flowability, have therefore been able to gain a foothold in this area. Metallocene grades are further characterized by a narrower molecular weight distribution compared to Z...

...the areas of product purity and freedom from emissions are coming into prominence. Some manufacturers such as Total Petrochemicals, Brussels, Belgium, with its Lumicene series, and Lyondell-Basell Industries BV, Rotterdam, Netherlands, whose Metocene series now includes copolymers, clearly believe that the hour of metallocene products has finally come. That said, Borealis AG, Vienna, Austria, has shown with its BorPure products that significant progress can still be achieved with a new generatio...
