Abstract

Abstract Copolymerisation of propylene with small amounts of other olefins in the presence of a catalyst comprising a metallocene of the formula I …<IMAGE>… and an aluminoxane gives a polyolefin wax in high yield. The wax is formed as compact spherical particles having a narrow particle size distribution and high bulk density. In addition, the physical data of this wax, for example the hardness, melting point, melt viscosity, etc., are variable within broad limits. …<??>The polymer chains have a similar and uniform structure, and the comonomer units are arranged predominantly individually between polypropylene blocks.
