Abstract
Process for producing poly-α-olefins are described wherein the processes comprise: (a) providing a primary alcohol; and (b) polymerizing the primary alcohol in the presence of an acidic alumino layer silicate to form a poly-α-olefin. Water formed during the polymerization can be removed, optionally during the polymerization, and subsequent hydrogenation may be performed.

A process for producing poly-α-olefins, comprising:
- (a) providing a primary alcohol;
- and
- (b) polymerizing the primary alcohol in the presence of an acidic alumino layer silicate to form a poly-α-olefin, wherein the acidic alumino layer silicate has an acid charge of from 3 to 300 mval/100 g.
A process for producing poly-α-olefins, comprising:
- (a) providing a primary alcohol;
- and
- (b) polymerizing the primary alcohol in the presence of an acidic alumino layer silicate to form a poly-α-olefin, wherein the acidic alumino layer silicate comprises an HCI-charged alumino layer silicate.
