Abstract
Copolymers of ethene and longer chained 1-olefins such as 1-octene, 1-decene, 1-dodecene, 1-octadecene and 1-hexacosene with 8 to 28 carbon atoms were carried out using [Ph2C(2,7)-ditertBuFlu)(Cp)]ZrCl2/MAO as catalyst. Precisely designed microstructures and activities up to 168 000 kgcopolymer/(molzirconocene·h·mol/lmonomer) can be obtained. There is a remarkable polymerization activity left even after a time of 4 hours. The incorporation of the longer chained 1-olefins reaches 19 wt% and depends on the chain length and the concentration of the comonomer in the feed, the LLDPE materials prepared show melting points of 129 – 112 °C.
