- the present invention relates to a novel process for the production of polybutadiene-containing moldings.
- Polybutadiene-containing moldings are mainly m the tire industry used as a molding strip for sidewalls or treads It is crucial that the surface is smooth and the edges are as free as possible.
- Polybutadienes having a high cis content and a polydispersity which is as small as possible are known to provide excellent properties to tire compounds, e.g. low rolling resistance or low tire wear.
