Abstract
Alpha-olefin oligomer is prepared by contacting an alpha-olefin monomer which contains from about 8 to about 16 carbon atoms with a heterogeneous catalyst system formed from (i) a solid olefin polymer having a linear backbone and a plurality of pendant omega-hydroxyalkyl groups, and (ii) a boron trihalide, preferably BF.sub.3. The catalyst system is stable and very reactive at relatively high temperatures, and the solid polymer of the catalyst system can be recovered and reused repeatedly in batch-type operations and can be used for long periods of time in continuous or semi-continuous operations.
